how to disable the builtin function "if"

[emicklei]

hi,

I am using expr for creating a DSL to program music melodies (melrōse.org) .

The version (v1.17.5) has support for the operator if else but this conflicts with my custom "if" function.

For earlier releases, I was able to disable functions:

for _, each := range []string{"join", "repeat", "trim", "replace", "duration", "map"} {
	options = append(options, expr.DisableBuiltin(each))
}

However, this does not work for the "if" operator. Please advice how to accomplish this.

Yes, if is an operator. I will add an option to disable if operators.
