in reply to FileHandles in a Hash

Just for you to know another trap of hashes of file handles, if you want to write to a file handle in a hash, you usually have to enclose the hash element between curly braces. For example:
print {FH_hash{$foo}} $line_out;
I tried to see if enclosing the file handle within curlies for reading with the diamond <> operator might work:
while (<{FH_hash{$foo}}>) { #...
but that does not help. Using the readline function is really the right solution.
