Global search and replace inside string

Hey all, I'm working on learning Perl 6 and am trying to write a little utility that will do a simple search and replace. Could knock this out in a few other languages quickly, but I really want to get to know Perl 6 better :) Anyway, so here's some pseudocode that I need some help writing. my

I think the strict answer to 'Is it correct?' is 'No'. The point being that 'my $x' gives $x type 'Any'. But practically, having type Any allows for $x to be assigned any value, be it Str, Int etc. So 'practically' the answer to 'Is it correct?' is 'Yes'. On Wednesday, March 22, 2017 02:07

The default type constraint is Mu, with a default of Any (everything is of type Mu, and most are of type Any) You shouldn't be able to change the type constraint of a scalar container (used for rw variables) Changing the type of a value, of course makes no sense. (a Str is always a Str, even
