Range-based code like you are using leads to *huge* numbers of function calls to get anything done. The advantage of inlining is twofold: 1) you don't have to pay the cost of the function call itself and 2) often more optimisation can be done once a function is inlined.
Thanks for that explanation! Now that you mention it it makes perfect sense. I never considered it, but of course *huge* numbers of function calls to e.g. next() and other range-methods will be made.
Because there are much better at inlining. dmd is quick to compile your code and is most up-to-date, but ldc and gdc will produce somewhat faster code in almost all cases, sometimes very dramatically much faster.
Sure sounds like I could have more fun with LDC and GDC on my system in addition to DMD :).
