Excessive compile times

This code was brought to my attention by an associate, Valentin Iamandi, who mentioned it was from Jonathan Kehayias ... we have a client who may be victim of a SQL Server compilation bug (3 seconds compile time, 75ms execution time, this is to identify other potential victims.
