Yeah, I just looked at this code. The problem is that I wouldn't do a straight, mechanical port to D, I'd D-ify the code a little while I was at it (such as making it work on generic random access ranges if it's an out of place transform, making real-only inputs vs. complex inputs DRYer with templates, etc.). Since this code seems to have been straight-up translated from FORTRAN, it scores about a -2 the readability scale, from 1 to 10. In other words, I would probably be able to translate it and make it run, but even the slightest modification would be near impossible.
