IMHO - yes. Looking up names is what python does all the time, trying to
microoptimize that away is silly. It is only justfied if you have
extremely timing-critical code.
And then, all you need to do is to say
_function = function
for value in values:
which will reduce lookup-time, as _function is found in locals() rather
And any function that does something worthy will dwarf the second
namespace-lookup I'd say.
