[RFC] ifsetor operator
Hello List,
i also agrre that an internal function is much better. And here is
it as such an internal function (that does not result in an expensive
function call).
Synopsis: "ifsetor" "(" value "," default ")"
Returns the value if it exists or a given default value.
Syntax: "ifsetor" "(" variable [ "," expression ] ")"
Semantic:
- The value in question must be a variable.
- The default value can be any expression.
- The default value can be omitted in which case NULL will be used.
