Re^8: Reason for this discrepancy with scalar?

But lexical types largely don't do what people expect; in particular, they don't stop something which isn't an Int or whatever from being assigned to the lex var; nor do they coerce the assigned value to that type.

In general, adding types to perl is a big topic which tends to trigger the occasional heated discussion on p5p and elsewhere.

Yes I remember digging into it and the `fields` Pragma. And .... `# this will generate a compile-time error my Foo $foo = Foo->new;` [download] I could see a use case in extending this already existing syntax for other purposes, like allowing to translate a subset of Perl to inline C helping IDEs to intellisense method expansions defining an initial type (e.g. for serializers ; sic) But probably I'm naive.

allowing to translate a subset of Perl to inline C

defining an initial type (e.g. for serializers ; sic)

But probably I'm naive.
