_equals

Do these parameters match? -- Function

_equals(EXP1, EXP2) -> YES OR NO

_equals produces Yes iff the expressions in the two parameters match each other. The definition of "match" is type-dependent, but by and large is similar to == in most programming languages.

Alternate version:

VALUE -> _equals(EXP) -> YES OR NO

This receives a VALUE, and tells you whether it matches the given EXP.

If you provide more than one value on either side, it will do all of the comparisons, and return all of the results. So for example, if you say:

<2, 3, 4, 5, 6> -> _equals(4)

the result will be false false true false false.
