Generators vs. Functions?

[Wolfgang Keller]

Hello,

in <dr86uc$8kt$1 at wake.carmen.se>, Magnus Lycka <lycka at carmen.se> posts the 
result of a short test that seems to indicate that resuming a generator takes 
more time than calling a function.

If this is actually also true in the general case, and not due to eventual 
non-representativeness of the test mentioned above, is it simply due to a 
less-than-optimum implementation of generators in the current Pyython 
interpreter and thus likely to change in the future or is this a matter of 
principle and will consequently remain like this forever?

TIA,

Sincerely,

Wolfgang Keller
