Re: What's this line means in HTTP::headers? ("the context")

[Anonymous Monk]

What "the context" refers here

"The context" is a fundamental feature of the language, like an array in scalar returns the size of an array

Also I know the context meaning in some cases saying

my $var = @array

But here in specific case:

return @old if wantarray;

Does that mean if wantarray is always true? since @old is always an array?

[Anonymous Monk]

No. wantarray has nothing to do with @old, it has to do with how sub header is called, in what context.

[anaconda_wly]

Yes, I know Auto-increment sign but just didn't understand the outcome here.
