Perl 6 “Amenities”

There are so many little delightful things that Perl 6 offers, so I'm gathering them into this note.

Regex Zero-width Matches
<same> yes Matches between two identical characters
<wb> yes Word boundary
<ws> no Whitespace, same as: <!ww>\s*
<ww> yes Within word
<ident> no Basic identifier (no support for ' or -). Same as: <.alpha> \w*
