Feature Proposal: Create function synonyms for long function names
Replacing long function names with a synonymic variable can be used to save a whole lot of characters if used frequently.

# Example
```lua
-- 81 tokens
-- 243 chars
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
printh(1)
```

This uses a lot of characters, so if you create a variable (`p`) that stores the function `printh`, you can save 126 characters at the cost of only 3 tokens.

```lua
-- 84 tokens
-- 117 chars
p=printh
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
p(1)
```

This would take effect on any focus except `Tokens` and `Tokens & Compressed Size`.
It saves a lot of characters *and* a few compressed size units (idk what to call them).
Only when focusing on tokens do the downsides outweigh the upsides.

It's technically even worth it for functions of length 2 (though there aren't any built-in functions that short), but it's more than worth it for length 3+ functions.
