Perl Issues

Our Developers wrote our Special Ed Student Info. application in Perl - 
about which I know zip.  Without going into gory details of why, their 
code repeatedly checks for the existence of specific tables (out of the 
150,000+ tables in our Production Student Info.) by doing 
"Select Count(*) From All_Tables Where Table_Name = '<TableName>'"
whick is very inefficient, especially with 150,000 tables.

First of all, I want them to not check for table existence and code in 
Exception Handling, but they are resistent to my suggestions.

Second, if they don't code the Exception Handling, I want them to use a 
utility function that we have that more efficiently checks for table 
existence and returns a Boolean - True if exists, False if not exists.

My two questions:
1.  Can Exception Handling be easily done in Perl?  If so, any good 
examples I can point them to?
2.  They say that Perl can't handle Boolean values.  Is that true?  Any 
guidance here?

Thanks.
