Not sure what they are referring to, but it may be that you can declare things as having one of several types (e.g. int|string|void) or even that something can be any type at all (i.e. turn off static type-checking for that thing)? I do not think the type-checker will ever randomly decide to just not check a type given that you have provided types for it to check, but it was a long time ago since I had to read or write any Pike code.

Looks like there’s a `mixed` type, variables of which can hold values of any type. But at least that’s something you can `grep` for.

A more subtle issue with type hints (as in TypeScript/Python, not sure if this applies to Pike) is that there are ways to work around the type system. You can get, for example, a variable of type `int` that actually holds a `list`:

I can turn off static type checking for a thing in C by using `void*`
