AgentRev: The behavior of "var1 isEqualTo var2" is pretty much equivalent to "var1 in [var2]", plus the ability to compare arrays, and slightly better performance.

Tajin: Simply put, "isEqualTo" is a binary comparison. Therefor it is very fast but only accepts 100% identical matches. In some other languages this is known as "===" instead of "==".; Posted on November 3, 2016 - 02:39 (UTC)
Dedmen: When comparing with nil result is Nothing. "nil isEqualTo player" returns "Nothing" instead of expected "false" diag_log [nil isEqualTo player]; Will print "[bool]"
