This isn't going to gain you much. It's the difference between:
[+ $fdat{foo} +]
and
[+ $foo +]
You could pretty easily write something like:
foreach $key (keys %fdat) {
eval("\$$key = '$fdat{$key}'")
...
That won't work as written, and of course you need to check for
illegal variable names, reserved variables, characters that have to
be escaped and the like. And while you're at it you might want to
change tab-seperated variables into arrays. Embperl's hash is a bit
more flexible because it doesn't have any of those restrictions, you
just have to type 7 extra characters.
P.S. You'd probably also want to make %fdat contain references to the
variables or vice versa, so that changing one would change the other.
Otherwise you'll lose a lot of the magic of %fdat.

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
