I was just looking over the upcoming talks in the llvm devroom at
FOSDEM, in preparation for Kai Nacke's talk about ldc in a couple
hours (you can stream it here: http://streaming.fosdem.org), when
I read about RubyMotion, which uses llvm to provide
native-compiled ruby apps for OS X and iOS:
http://www.rubymotion.com/features/
It is commercial and partially open source, a model I've
suggested for D before:
https://github.com/HipByte/RubyMotion
There are a lot of mobile devs looking for a better programming
language in that booming field and D is really missing out by not
being on mobile, where its ease of use and efficiency would
really shine. This would be a great opportunity for someone to
port D to iOS and provide a similar, partially closed commercial
implementation.
