Validates a function with strict equality, by wrapping the function and checking
its parameters and return value through validateEquals function. If some
parameter or return value does not match the expected type, it returns
IValidation.IError typed object. Otherwise there's no type error, it
returns IValidation.ISuccess typed object instead.
For reference, IValidation.IError.path would be a little bit different with
individual validateEquals function. If the IValidation.IError occurs
from some parameter, the path would start from $input.parameters[number]. Otherwise
the path would start from $input.return.
$input.parameters[0].~
$input.return.~
By the way, if what you want is not finding every type errors, but just finding
the 1st type error, then use assertEqualsFunction instead. Otherwise, what
you want is just validating parameters or return value only, you can use
validateEqualsParameters or validateEqualsReturn instead.

On the other hand, if you want to allow any superfluous properties, utilize validateFunction or assertFunction instead.
