This is a difficult question - one way to measure - more or less objectively -
is to somehow figure out how many machine instructions (on some "standard"
machine - Turing?) would be generated by the code....
Even that won't tell us much - cos it will favour inline code as somehow
"heavier" than looping code...
Now we know that inline code is faster on most machines, and looping code is
more compact, - so how to say what is best?
And this only covers what you computer scientists call the "procedures" or
"methods" - the actual instructions that are executed by the machine - how is
the memory space used to be measured and factored in? - and the running stack
space needed? - specially in the case of recursions....
And then how do you handle an interpreted language vs a compliled language - do
you count the machine instructions of the interpreter, or only the ones actually
executed? - and the memory consumed by the interpreter?..... - And if you count
the interpreter, why not the compiler?...
Not simple, not easy - in fact it's a minefield....
