Proposed Perl 6 while/until documentation. Also planning to place this *above* repeat/while and repeat/until

whileuntil.txt

The C<while> statement executes the block as long as its condition is
true. So

=begin code

my $x = 1;
while $x < 4 {
print $x++;
}
print "\n";

=end code

produces

=begin code

123

=end code

Similarly, the C<until> statement executes the block as long as the
expression is false.

=begin code

my $x = 1;
until $x > 3 {
print $x++;
}
print "\n";

=end code

again produces

=begin code

123

=end code

The condition for C<while> or C<until> can be parenthesized, but there
must be a space between the keyword and the opening parenthesis of the
condition.

Both C<while> and C<until> can be used as statement modifiers. E. g.

=begin code

$x++ while $x < 12

=end code

Also see C<repeat/while> and C<repeat/until> below.
