Re: Parsing barewords as sub/method calls? (workaround)

Well found kind of a workaround:

In the case of arguments for a undeclared bareword putting parens around them is mostly acceptable (syntactically sweet enough)

And without arguments prepending an ampersand helps.

This works w/o messing with strict.

use strict;
use warnings;
use feature 'say';


our $AUTOLOAD;

sub AUTOLOAD { say "Autoload called as $AUTOLOAD(@_)" }


BLA(1,2,3);

&BLA;

no strict 'refs';

#&BLA 1,2,3;

__END__
Autoload called as main::BLA(1 2 3)
Autoload called as main::BLA()

update

thanks for pointing out the special meaning of &NAME;, I was aware of it and as Eily pointed out, it's not a problem in this special case.

Note that `&BLA;` has the interesting side effect of passing `@_` through: `use strict; use warnings; use feature 'say'; our $AUTOLOAD; sub AUTOLOAD { say "Autoload called as $AUTOLOAD(@_)" } sub BLUBB { say "BLUBB called with @_"; &BLA; }; BLUBB( 1,2,3 );` [download]	[reply] [d/l] [select]

&BLA; is actually equivalent to `BLA(@_);`. This works in your case because @_ is empty, but if you use this syntax within a sub, you'll forward its arguments. `use feature 'say'; @_ = qw/4 5 6/; our $AUTOLOAD; sub AUTOLOAD { say "Autoload called as $AUTOLOAD(@_)" } BLA(1,2,3); &BLA; __END__ Autoload called as main::BLA(1 2 3) Autoload called as main::BLA(4 5 6)` [download]	[reply] [d/l] [select]
