Below is a good reason to turn them off after it's debugged... Same as above, gut with type-checking turned off: integer assigned to Object 10000000 times, et: 0.84 integer assigned to Atom 10000000 times, et: 0.91 Iinteger assigned to nteger 10000000 times, et: 0.75 Sequence assigned 10000000 times, et: 1.21 Function call return assigned to integer 10000000 times,et: 3.61 integer assigned to EuType 10000000 times, et: 0.85 Looks like "without type-check" is worth doing only if you have user-defined types. Using an atom (123456789.01) where legal: atom assigned to Object 10000000 times, et: 0.95 atom assigned to Atom 10000000 times, et: 1.17 -- -- function call return assigned to object 10000000 times,et: 4.16 atom assigned to EuType 10000000 times, et: 5.35 Irv
