541a4f1628e4e156f6eefc547938746f7b736104 is the first new commit
commit 541a4f1628e4e156f6eefc547938746f7b736104
Author: Jonathan Worthington <jnthn@jnthn.net>
Date:   Mon Jan 7 17:30:58 2019 +0100

    More aggressive scope flattening
    
    Previously, we would only ever flatten away lexical scopes if we saw
    that there were no declarations inside of that scope, the only special
    case being `$_`, which was handled specially. There was also some
    special mechanism in place to try and handle topic rebinds correctly.
    
    Recently, lexical to local lowering became more powerful, able to deal
    with normal lexical variables rather than just parameters and name
    bindings. This handling takes in $_ too.
    
    This commit replaces the scope flattening mechanism with one that, at
    its heart, will flatten in an immediate block if all of its variables
    were lowered. This means that in a program like:
    
        my $a = 42;
        if $a > 21 {
            my $b = 10;
            if $b < 200 {
                say $a + $b
            }
        }
    
    Then both of those scopes flatten away, thanks to both `$a` and `$b`
    having been lowered. Previously, only the innermost one would have been,
    thanks to the declaration of `$b`.
    
    Since the `$_` in each block is now also lowered to a local when
    possible, then we can replace the `getouterlex` calls with a simple
    bind, and do away with the topic preservation mechanism, which was
    always rather cheaty.
