Kronzky

A conditional assignment can be done via the following syntax:

_msg = if (alive player) then {"you're alive"} else {"you're dead"}

Alef

It's possible to assign to Numbers. Numbers values are not changed. Useful instead of assigning to nul or nil when a result is of no use.

[player] execVM "myScript.sqf"

Dedmen

This operator actually does not return a Nil. It really returns pure Nothing. Not Nil Nothing.
This can cause problems. For example:

_var1 = call {
    _var2 = "";
};

The return value of the "call" is the return value of the "=" operator.
If it were a nil then of cause "_var = nil;" would work just fine.
But in reality this causes a "Generic Error in expression" because you can't assign pure Nothing to anything
