I normally do not declare different types of variables with the same name, eg,  %skedhash, $skedhash, but that is what it is (and completely allowed in Perl).... what is happening here?:

sub sked {                #LN44
    no warnings "uninitialized";
    %skedhash = @_;
    say "In sub 'sked'";                #LN44

That looks like an invalid statement before the skedhash assignment. Could be a problem?

Update: Maybe that is ok? Not sure since I cannot run the program or see the line that the compile fails at (what is line 65?).
