Can't transfer issue across orgs, so just link it here

For starter it would be nice to remove misleading information from documentation:
https://docs.sannybuilder.com/language/functions#function-body
I do not see mention that function declaration can not be placed in code execution path.
It should be explained at least once, then every later example could split declaration and call into two separate code blobs.
