#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

is it possible to write a Rust macro that transforms:

macro!(value => {
  a => b,
  c,
  d => e,
  f,
})
// with repetition of either declaration format

into

match value {
  a => fn(b),
  c => fn(c),
  d => fn(e),
  f => fn(f),
}
// etc
