[E2] Internal error but no compiler error/warning when trying to do operations on not-yet-defined variable

[CheezusChrust]

Describe the bug
sv: Expression 2 (oops): Internal error 'entities/gmod_wire_expression2/core/number.lua:81: attempt to perform arithmetic on local 'lhs' (a nil value)' at line 8, char 1

To Reproduce

@name bug
@strict

function bruh() {
    Piss = 5
}

print(Piss + 2)

Expected behavior
A compiler error or something

Oh god are you the same cheeze that made the horribly uncompressed button textures?

This is intentional since @strict doesn't replace globals every time now, but I think it really should initialize on the first go, at least, since that wouldn't cost much.

That or make the compiler not stupid and include the scoping when deciding if a variable has already been assigned to. I'd prefer that.

ie

wire/lua/entities/gmod_wire_expression2/base/compiler.lua

Line 1023 in 4038ae0

existing.initialized = true

should also write down the scopeid it was initialized at (careful to only assign if currentid < assignid), then just check if assignid < currentid when checking if the variable is initialized or not.

Then you'll at least get a warning in advance.
