Re: [Parseperl-discuss] How should "for qw<blah> {}" parse?

[Chris D. <ch...@ch...>]

Elliot,
Are you sure that's valid syntax?  I don't think it's legal to omit  
the parens.

% perl -le'for qw<a b c> { }'
Missing $ on loop variable at -e line 1.

Did you mean "for (qw<a b c>) { }" ?

% ppidump 'for (qw<blah>) { }'
PPI::Document
   PPI::Statement::Compound
     PPI::Token::Word    'for'
     PPI::Structure::ForLoop     ( ... )
       PPI::Statement
         PPI::Token::QuoteLike::Words    'qw<blah>'
     PPI::Structure::Block       { ... }
