A clear and concise description of what the bug is.

This script works:

version "4.13"

class Test
{
    Function<play void()> f;
}

but change class to struct, and you get:

zscript.txt:zscript.txt, line 5: Invalid Scope for Function Pointer

Only clearscope seems to work; neither play nor ui does. Changing the scope of the struct itself to play or ui does not appear to have any effect either.

However, it is possible to work around this by declaring the type as Function<void>, but then a cast to the proper type will be necessary in order to call the function declared this way. Which makes me think this is likely a bug in the compiler and not some kind of fundamental limitation of the ZScript architecture.

Steps to reproduce the behaviour.

1. Load the Zscript file provided in the description
2. Observe that there is no error
3. Change class to struct in the script code and try again
4. Observe the error: "Invalid Scope for Function Pointer"

hmm, that shouldn't be triggering at all since it's defined as play scope, is the parser doing something funky to struct members?
