=:= is exact equality as used in pattern-matching, == is "value
equality" where in addition integers compare equal to same-valued
floats.

Generally use the exact operations =:= and =/= unless you're certain
you want the variants with implicit numerical conversions.  There's
also a slight performance benefit to the exact operations.
