This is certainly possible, but I imagine it's not going to happen except as an outside project.
Making a compiler like this isn't exactly easy, either – you'd probably have to do a lot of reaching into Julia's C internals to get to the type-inferred code. You're welcome to try this, and I'm sure that you'd be able to find help on the mailing list for the trickier parts, but it might be best to wait until we have static compilation and link against Julia code as a library – you can avoid the run time that way. – Mike On Sunday, 11 May 2014 15:43:14 UTC+1, francoi...@gmail.com wrote: > > Hi Julia users, > > As a newcomer, let me first introduce myself.
