Jarrett Billingsley: >I'm talking 60-70 seconds to compile a more complex regex.< A modern CPU is able to do something like 60*2*2E9 operations in that time, DMD needs 6 seconds or less to compile about 60000-80000 lines of my D code, so I think it's a bit too much time (probably 100 or 1000 times too much).
