Error when using `sum` on array of floats #83

Closed mcintyre94 closed 1 year ago

mcintyre94 commented 1 year ago

Example code:

from seahorse.prelude import *

# This is your program's public key and it will update
# automatically when you build the project.
declare_id('FLwzxcGsWo28gVDA7oGHd15sSnmY6kvP8kziJ6gQqCnC')

@instruction
def ix(sig: Signer):
  a = array(1.0, 1.5)
  s = sum(a)
  print(s)

Error seems to be coming from here: https://github.com/ameliatastic/seahorse-lang/blob/e1178ed959246417255321a4cbe5b55431a75994/src/core/compile/builtin/python.rs#L519-L523

This might be tricky to fix because the comment suggests we don't have type info about the array there
