  • state variables No more scoping variables with an outer curly block, or the naughty my $f if 0 trick (the latter is now a syntax error).
I think you mean "static variables". A state variable is, generally, just a global variable, typically those used by the system, for example all those variables (with a special name) in perlvar.

    I think the OP means "state variables" as that's what they are called in Perl 6. The declarator is the word state too.

    sub foo { state $x = 0; # $x will retain it's state through # successive invocations of foo() # ... }
    (Yes, other languages use the keyword static, but this is Perl!)
