Don’t you get this from most macro assemblers? I know I’ve seen some very old and crusty ASM that nevertheless does structured programming and even limited OOP through macro-ASM facilities.

(That being said, symbolasm looks 1000x more ergonomic and “also communicates developer intent”-laden than any macro ASM ever did; and also is probably something you could learn once, while a project’s macros are specific to said project.)
