I am aware that id is a built in function why shouldn't i use it?
Replaceing lambda with id was intended as an performance hack. Profiling
proofed that lambda itself takes more than twice as much cpu time than id
alone. (profile shortened)
3610503 function calls in 22.451 CPU seconds
Ordered by: standard name
ncalls tottime percall cumtime percall filename:lineno(function)
960096 4.593 0.000 6.702 0.000 test14.py:33(<lambda>)
1 0.003 0.003 22.451 22.451 {execfile}
960096 2.109 0.000 2.109 0.000 {id}
However using lambda seemed useless to me since id already took an argument
and wrapping it in an python function simply has no real purpose.
