- 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 following 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 following expression:hello = 10
If the assignment operator was a regular operator, hello would first evaluate to nil and finally nil = 10, which wouldn't make a whole lot of sense.
To work as a regular operator, and like any other operator requiring a reference to a variable rather than the variable's value (Eg. isNil), its syntax would have had to be."hello" = 5
