in thread why does Perl eval have a strange terminator?

I think I'm beginning to understand where you're coming from.

Try/Catch in other languages is a compound statement, and the new Perl feature is also implemented as such.

But

  • eval {BLOCK};

isn't, it's function like.

I think that's at least partly due to sharing its name with

  • eval "string";

in Perl.

Actually it's quite surprising for many coming from other languages, that we call it "eval".

Larry often loved to "recycle" concepts.

    It's due to it returning a value. That makes it an expression.
