Note that "in an array or other expression".  I've always thought the
intention of this phrase was "you _could_ help the parser by doing this,
if you have expression more complex than a simple scalar variable
reference".

IOW, I know that {} _can_ be used there, but I haven't seen people write
{$a_single_variable}, especially without a space around the "expression"
(technically, a single variable is an expression), when

	print $fh <stuff>

suffices, and I was curious why you chose to use the syntax when it wasn't
necessary.  Besides, {$fh} looks so eh... (hesitates to mention a dirty
word ^W^W^Wthe name of a different language, but bleeps it out)...
