Re^2: Use function as a regex

You can probably use straight-up $str =~ re() syntax with global searches as well, just make sure the re() returns a :lvalue. Either that or return a ref: $str =~ ${re()}.

I don't see any connexion between :lvalue and /g. `$str =~ ${re()}` isn't a global search but the output of qr is already a reference so /${re()}/g works, as pointed out by salva.	[reply] [d/l]

Embarrasing. I read it exactly backwards. Something like `while (str() =~ /(.)/g)` can be made to work by using `sub str :lvalue { state $x = "abcd" }`. Sorry about the noise.	[reply] [d/l] [select]
