Re: How to call a sub-routine ref

Is the first one even correct? I get the Useless use of private variable in void context warning, when warnings are enabled.

Or, did you mean to say:

  &$ref();

I prefer the second one, as it feels more consistent with the way the other references are used as well:

  $aref->[...];   # as opposed to @$ref[...]
  $href->{...};   # as opposed to %$ref{...}

You are right, I forgot the "&". Fixed. And I agree with what you are saying. There are no stupid questions, but there are a lot of inquisitive idiots. -- greengaroo	[reply]
