DLX is really just what the logo portrays; you take Ruby as a basis and then try to fit in C as elegantly as possible, without it causing too much of a distraction.

Interface first, implementation later

For me —and thus for Ruby/DLX— the interface that DLX offers, is more important than the actual implementation. The interface should be intuitive and easy to use and, like ruby on rails, should use convention over configuration. This means that, where possible, DLX is expected to do the right thing, and if this is not the case, the user must be able to change it for such cases. There is a saying for this: Making the common case easy and that's what DLX basically is all about.

Ofcourse there are disadvantages to this approach. The first implementation was a huge ruby beast built around Ruby/DL(2). It was dead slow and the main reason for a rewrite of the core in C. Ruby/DLX 0.9.0 is going to be the first release that uses this new core. It's much faster, but the implementation is still not 100% up-to-par with the interface: Currently DLX eats quite some memory, because —in the true nature of the above philosophy— not much attention has been paid to memory management and some conservatism in this part should be added for the next release (0.9.1 probably).
