BabyHint does not differentiate between locally defined functions and global processing-js functions

Perhaps this is a mutation of issue 445? See the simple test program https://www.khanacademy.org/computer-programming/wat2/4562973953228800 that declares a function called arc inside of another function and attempts to invoke it. Yoko Oh Noes whines about Processing.js arc which is unrelated.

Start by reviewing the related issue 445 and reproducing the linked Khan Academy test program. Trace how BabyHint resolves a locally declared nested function named arc versus the global Processing.js arc. Done means the local call is no longer reported as an unrelated global-function error.
