Complicated language structure? Long compilation times?
I can attest that on certain types of projects (i.e. template
heavy), D's lightning fast compilation time goes out the
window. It has improved greatly, but there are still some
improvements that can be made.
For instance, dcollections, which is about 10kloc takes 17
seconds to compile all the unit tests. It used to be well over
a minute, till walter changed a linear lookup to a hash lookup
on the symbol table. There's an outstanding issue which is
similar still in bugzilla:
Meh, that's still nothing compared to C++. The sample games
included with
Marmalade and the Marm-based IwGame engine take *serveral*
minutes to
compile - and those are just sample programs!
Template-heavy projects don't throw D's lightning fast
compilation times out
the window, it just makes them less lightning-like. It's still
an order of
magnature faster than equivalent, or even merely similar, C++.
I remember g++ taking dozens of minutes on a SINGLE compilation
unit on FreeFEM++, a very heavily templated project. Large C++
projects with lots of templates can take several hours to
compile. So one has to be very careful with libraries like Boost
on large projects, compilation times can explode.
