The error I get:
---------------------------------------------------------------
Use of uninitialized value $algo in lc at
/home/a/perl5/lib/perl5/File/RandomLine.pm line 103 (#1)
(W uninitialized) An undefined value was used as if it were already
defined. It was interpreted as a "" or a 0, but maybe it was a
mistake.
To suppress this warning assign a defined value to your variables.
To help you figure out what was undefined, perl will try to tell you
the name of the variable (if any) that was undefined. In some cases
it cannot do this, so it also tells you what operation you used the
undefined value in. Note, however, that perl optimizes your program
anid the operation displayed in the warning may not necessarily appear
literally in your program. For example, "that $foo" is usually
optimized into "that " . $foo, and the warning will refer to the
concatenation (.) operator, even though there is no . in
your program.
---------------------------------------------------------------
The solution (as far as I can tell) would be to put parentheses to have
perl call lc as a function, or to remove lc.
