A conditional assignment can be done via the following syntax: _msg = if (alive player) then {"you're alive"} else {"you're dead"}

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. 0 = [player] execVM "myScript.sqf"

The assignment operator is the only operator that isn't really an operator. It is a special construct.
Take for example, the expression "hello + 5". Assuming hello contained the value 10, "hello" would evaluate to 10, and "10 + 5" would finally evaluate to "15".

Which is why the assignment operator wouldn't work as a regular operator. Take for example, the expression "hello = 10". If the assignment operator was a regular operator, "hello" would first evaluate to nil and finally "nil = 10" wouldn't make a whole lot of sense.

To work as a regular operator, its syntax would have had to be:
"hello" = 5;
Just like any other operator requiring a reference to a variable rather than the variable's value (Eg. isNil).
