I suppose initializing the runtime takes a lot of time. When
making a simple command line utility, half a second of delay is
highly undesirable.
Are there ways to reduce this to below 0.1s, or should I just
leave idiomatic D and make a betterC program?
It's not necessarily the runtime that's slow.
Besides if it was and it took 1 second to startup, then it
wouldn't matter in practice with an actual application.
Besides there could be a lot other factors.
Without actual compiler versions, compiler flags and example code
then it's pretty much impossible to tell what's slow.
For me it's certainly not that slow with dmd.
