Re: Prevent Strings From Being Interpreted As A File Handle

The simple solution is to stop calling a subroutine as a method and just use: Input::awesome;.

Or, if awesome really is a method, then invoke it via a reference blessed into the class 'Input':

$o = bless [], 'Input';;
...
$o->awesome;;
Yay!

Or, as you've pointed out, use lexicals.

Thank you for coming up with the instance workaround. However, I am not trying to prevent this ambiguity, but to resolve it in a specific way (i.e. I'm seeking Perl wisdom, not trying to solve the immediate problem which I'm already mitigating using other means). In general, Perl is flexible enough to change such core behavior, and I would like to find out how this can be done. I was very careful to word my question as “How can I disambiguate a method call on a string so that it is always resolved as a class method call, and not as a call on an IO instance?” – both “method call” and “string” are central to my question.

both “method call” and “string” are central to my question. I covered your objections with my last sentence: Bottom line: stop going out of your way to artificially create problems. Even if you succeed in finding a way to subvert Perl into doing this stupid thing; it won't stop it being stupid.
