... a way to turn off this particular error message from warnings,
while leaving other feedback functional.
no warnings 'uninitialized';
See warnings or, in older Perl versions, perllexwarn.
... have to define every possible value in a hash before it might
possibly be assigned one--which is where I usually get these
"warnings."
I don't understand this statement. Can you give an example of a
situation in which you cannot assign a value to a hash key without
producing an 'uninitialized' message unless the key already
exists (with another value, of course). This is the situation that
is brought to my mind by the quoted statement. (Please see
SSCCE.)
