whitespace not allowed between sigil and identifier

[moregan]

Perl allows whitespace between a sigil and its identifier, but PPI doesn't support it. @ foo is the same as @foo and should parse as PPI::Token::Symbol, but doesn't:

$ ppidump '@ foo'
                    PPI::Document
                      PPI::Statement
[    1,   1,   1 ]     PPI::Token::Cast         '@'
[    1,   3,   3 ]     PPI::Token::Word         'foo'

There was a reason for this. I think I was trying to avoid the problem of dealing with the whitespace by treating it kind of like a fake soft reference. I.E. @{foo}

I felt at the time that the space was such a strange case that it wasn't worth supporting, and I don't recall encountering it more than once or twice ever in the wild.

A tinderbox search run over CPAN would confirm if anyone ever uses it.

Had to go to backpan to find PPI::Tinderbox, and the latest there is 0.08. Was that the last release (January 2005)?

Probably. There are other modern equivalents, I think dagolden has a cpan scanner and then I wrote a derivative of it. So it might have a different name On Jan 1, 2015 5:54 AM, "moregan" [email protected] wrote:
