     51== Change behavior of find_lex opcode == 
     52 
     53=== Description === 
     54 
     55The find_lex opcode no longer throws an exception when the lexical is not found; it returns PMCNULL instead. 
     56 
     57--- Rationale === 
     58 
     59This is consistent with the other "lookup" opcodes. 
     60 
     61=== Replacement === 
     62 
     63If you want to throw an exception, you must check the result of the opcode and throw the exception explicitly.
