Re: Re:{3} Eval and $@% ...

[srawls]

Look at perlref. GLOBs are Handles in general, so read them in array context with brackets like I did.

Only when used as a filehandle. For a variable name there is a scalar ($), a list (@), a hash (%), a filehanlde, and a format. Instead of saying:

$foo=$bar;
@foo=@bar;
%foo=%bar;

you can just say:

*foo = *bar;

So, when you dereference a type glob, you don't add the <foo> unless you are reading from a file handle.

No, you can't "just say" that

$foo=$bar;
@foo=@bar;
%foo=%bar;

and

*foo = *bar;

are equivalent. The first set of assignments sets $foo, @foo and %foo from the values of $bar, @bar and %bar, and that's it. If you later assign to $bar or $bar [3], $foo and $foo [3] remain unchanged. However, with the glob assignment, $foo, @foo and %foo become aliases for $bar, @bar and %bar. Modifications of the one are reflected in the other.
