I had the same issue as well. I wrote a class (attached) to encapsulate
references to routines via the name so that I could lazy-load them (this
is useful for template systems to avoid loading every possible tag
implementation every time). The logic tries to load the package for the
symbol if n
The easiest way is to call prototype. It dies if the
function doesn't exist.
sub function_exists {
eval { prototype $_[0] };
return ! $@
}
if ( function_exists("whatever") ) {
...
}

It would probably be safer to use a hash table for that.

Hi
I am writing a perl code which automatically forms
a function name using certain criteria and then calls the same
I have a run time error reporting function not
existing, if the function as such did not exist
But I would like the execution to continue
searching for other functions
So, is
