Moar weird EXPORT weirdness.md

So after that last bit of EXPORT weirdness, I went to apply lessons learned to the actual project, and the bloody error returned. I have now linked the cause to specific require statements:

sub EXPORT(+@a) {
        # cw: Implement SELECTIVE loading if necessary.
        @color_list = @a.elems > 0 ??
                @color_lists_found.grep(@a.any)
                !!
                @color_lists_found;

        #if $color_support {
        #       require Color;
        #}
        #for @color_list -> $cl {
        #       say "L: $cl";
        #       require ::("Color::Names::{$cl}");
        #}

        # cw: What we always export.
        #
        #     Is there any way to get EXPORT::DEFAULT from the module block?
        {
                '&lists_available'      => ::('&Color::Names::lists_available'),
                '&lists_loaded'         => ::('&Color::Names::lists_loaded'),
                '&location'                     => ::('&Color::Names::location'),
                '&color'                        => ::('&Color::Names::color'),
                '&hex'                          => ::('&Color::Names::hex'),
                '&rgb'                          => ::('&Color::Names::rgb'),
        }
}

If I run the project with the subroutine definition above, it works:

$ perl6 --stagestats -Ilib -e 'use Color::Names "Cloford"; dd color("red")'
Stage start      :   0.000
Stage parse      :   0.701
Stage syntaxcheck:   0.000
Stage ast        :   0.000
Stage optimize   :   0.001
Stage mast       :   0.006
Stage mbc        :   0.000
Stage moar       :   0.000
Nil

However, if I edit the sub to look like the following:

sub EXPORT(+@a) {
        # cw: Implement SELECTIVE loading if necessary.
        @color_list = @a.elems > 0 ??
                @color_lists_found.grep(@a.any)
                !!
                @color_lists_found;

        if $color_support {
               require Color;
        }
        for @color_list -> $cl {
               say "L: $cl";
               require ::("Color::Names::{$cl}");
        }

        # cw: What we always export.
        #
        #     Is there any way to get EXPORT::DEFAULT from the module block?
        {
                '&lists_available'      => ::('&Color::Names::lists_available'),
                '&lists_loaded'         => ::('&Color::Names::lists_loaded'),
                '&location'                     => ::('&Color::Names::location'),
                '&color'                        => ::('&Color::Names::color'),
                '&hex'                          => ::('&Color::Names::hex'),
                '&rgb'                          => ::('&Color::Names::rgb'),
        }
}

I get the following error:

$ perl6 --stagestats -Ilib -e 'use Color::Names "aa"; dd color("red")'
Stage start      :   0.000
Stage parse      : ===SORRY!===
Cannot find method 'merge-symbols': no method cache and no .^find_method

If you want to see this error in action, you can download the repository from here: https://github.com/Xliff/p6-color-names

So is this an error in Rakudo or an error in my code?

Thanks!
