I am starting a project to rewrite some of our internal tools from Perl to D. I chose D because I'm pretty excited about the design philosophies of the language. I've been programming for a long time and used a lot of languages, from assemblers to high-level (mostly C) to scripting languages (mostly Perl), and D is the first language I've been enthused about learning in many years.
I decided to move to a compiled language for one main reason - security. Functionally, Perl works quite well for the toolset I work on, but it's insecure - anyone that can run a script can also read, copy and create their own modified version of the tool. (And they do.) I know there are circuitous methods to get around this problem (sort of), but to be honest I don't have enough hours in the day to manage all of that and still get my primary job done.
