README

letUtils

Immutability is good. But one day I got tired of repeating variable names over and over again:

let fib = block: # OK, we are going to declare `fib`.
  var fib = @[0, 1] # I already got it will be `fib`, thanks.
  for i in 2 ..< 13:
    fib &= fib[^1] + fib[^2]
  fib # Once again? Really?

So I wrote a bunch of macros that handle the boilerplate. Now we can do this:

import letUtils

freezeVars:
  var fib = @[0, 1]
  for i in 2 ..< 13:
    fib &= fib[^1] + fib[^2]

echo fib
assert not compiles (fib[0] = 123)

Look at the documentation for more goodies.
