it's (a natural consequence of) spec, so I'll ask here on p6l instead.
I already know I can do all of the following:

$a.=postcircumfix:<[ ]>(42);
But can I
How is "character counting" done in Perl 6?
In Perl 5, it is `scalar tr/CG//` if I want to count the number of Cs
plus the number of Gs in a string.
S05 describes tr/// in terms of the .trans function, a handsome but
