<function name="Either" parent="Global" type="libraryfunc"> <description>An 'if then else'. This is `almost` equivalent to (`condition` and `truevar` or `falsevar`) in Lua. The difference is that if `truevar` evaluates to false, the plain Lua method stated would return `falsevar` regardless of `condition` whilst this function would take `condition` into account.</description>⤶ <description>A compact 'if then else'.
