# Module 'testall'
#
# Python test set, should exercise:
#	- all lexical and grammatical constructs
#	- all opcodes from "opcode.h"
#	- all operations on all object types
#	- all builtin functions
# Ideally also:
#	- all possible exception situations (Thank God we've got 'try')
#	- all boundary cases


TestFailed = 'testall -- test failed'		# Exception

# Part 1.  Test all lexical and grammatical constructs.
