# how would I go about making a macro or template that would allow me to shorten
# this:
for i in 0..<len(characters):
    let character = characters[i]
    # use character
# to something like
forEach(characters, character):
  # use character
# I can't simply do
for character in characters:
  # use characters
# cause the I get 'character' is of type <lent ref Character> which cannot be
# captured as it would violate memory safety (I'm trying to capture it in an `any`
# closure)
