Using an integer (123456789)

integer assigned to Object 10000000 times, et: 0.82
integer assigned to Atom 10000000 times, et: 0.9
Integer assigned to integer 10000000 times, et: 0.75
function call result assigned to integer 10000000 times,et: 3.81
integer assigned to EuType 10000000 times, et: 4.58

Your program takes quite a hit, if you write user-defined type checking
routines. 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
