It's a little misleading to claim that the first snippet works. Enable strict and you get

$ perl -Mv5.40 -e'my $x= Inf; say $x' Bareword "Inf" not allowed while "strict subs" in use at -e line 1. Execution of -e aborted due to compilation errors.

So we're talking about barewords, and barewords can only start with a subset of word characters. "∞" isn't a word character.


Does anyone else feel like this ought to get fixed? How likely is a patch for this to get accepted?

What fix are we talking about?

Changing the definition of bareword to include some symbols? Absolutely not.

Changing the type of character ∞ is in Perl to be different than in Unicode? Absolutely not.

Changing the definition of type of character ∞ is in Unicode? Absolutely not.


Perhaps you meant to compare to builtin::inf. It was added in 5.40, and it's still experimental, but I expect it to be imported by use v5.xx in the future. Adding ∞ as an alias for that is a completely different story. That would make more sense, and is entirely feasible.
