#macro_rules!

Right methodology, not nearly powerful enough

#proc_macros

Lisp-like methodology, but syn crate and DIY the AST, more importantly, the unholy diabolical compile times involved

#crabtime

idk, give reviews

Only if they learned from #Zig's #comptime/ #OCaml's #ppx

LET ME WRITE #RUST **AND** MANIPULATE ASTs, NOT AN XOR OF THEM
