Hi there! I am working on a library of functions that print different HTML tags, given non-HTML text arguments. (Some might think it's kind of stupid since there are already modules that do this, but it's turing out to be a great way for me to get really down and dirty with the Perl -- and I am digging it!) It's working great so far! Except that I think I hit upon a hitch and may have discovered what is either a shortcoming (probably intentional) in Perl or in my implementation (more likely the case.) The issue revolves around passing a subroutine as part of a text string that forms the argument of a call to another subroutine. Here's the code: 
# The main subroutine in question
sub MessagePrinter
{
    my(@logmessages) = @_;

    ULStart();
        foreach $message (@logmessages)
            {
                LI(); 
                Strong($message);
                         }    
    ULEnd();
}

############################################
# Suppporting subroutines

sub ULStart
{
    print "<UL>";
}


sub LI
{ 
    my($inputValue) = @_;
    print "<LI>$inputValue\n";

}

sub ULEnd
{
    print "</UL>";

}

As stated above, everything works great (unless I have inadvertantly introduced some typos.) But... I would be happier if I could issue the call to LI() in the sixth line of PrintMessage(%
