py5 rejects valid static mode code

[hx2A]

from py5coding/py5book#122

This code:

size(200, 200)

def draw_random_circle():
    x = random_int(width)
    y = random_int(height)
    circle(x, y, random_int(25))
    
for _ in range(20):
    draw_random_circle()

Doesn't work in py5bot or with run_sketch. The draw_random_circle() function messes up the code evaluation because it matches the regex ^def draw[^:]*:.

Somehow I remember changing this code because of a bug @villares reported, where def draw () , which is valid Python, was getting skipped over when it should not.

So this bug has been in py5 for a while and we did not notice it until now.
