Maybe the following enhancement of timeit would be worthwhile?
$ cat timeanyfunc.py
from mytimeit import Timer
def functionA():
print "Function A"
def functionB():
print "Function B"
T1 = Timer("f()", ns=dict(f=functionA))
T2 = Timer("f()", ns=dict(f=functionB))
T1.repeat(3, 1)
T2.repeat(3, 1)
$ python timeanyfunc.py
Function A
Function A
Function A
Function B
Function B
Function B

By the way, haven't we been there before, two years ago?
