Need Help??

entropy has asked for the wisdom of the Perl Monks concerning the following question:

$a=*{};    # doesn't like that
$a=*{''};  # that seems like a completely different glob!
$a=*;      # oops! - the * eats the ;
$a=(*);    # doesn't like that either

`$a = *;` [download] `$` is a deprecated variable used for regexes.	[reply] [d/l]

Wow, that clears it up. I had done '$a=' in the debugger, which causes 'print $a' to show it as a glob (main::;). I suppose the trick is that the debugger took it upon itself to add a couple of semi-colons in there, making it '$a=;;' or in other words '$a={";"};'.	[reply]
