One of the pitfalls of macro programming is that it gives the impression of lambda calculus efficiency without having it so one ends up spending a lot of time figuring out trivialities, which is why eventually was added, I gather.

Indeed computer tend to have natural life cycles, after they have matured, further development becomes difficult.

Other survivors are C, C++, Scheme. With TeX, change may start as with Lua, only some better syntax for text input.

I experimented a bit with giving Guile a C++ API, and then then there is a problem with that that C++ is statically typed whereas Guile is dynamic. For example, Guile does not distinguish statically between different types of numbers: integers, rationals, etc, so the proper way from the point of C++ is to only have open number type. But static typing is important in optimization.

And giving implement traditional function syntax on top of Guile does not work well, because (f, x_1, …, x_k) does not correspond semantically exactly to f(x_1, …, x_n). And there is a problem with the Scheme strict evaluation.

So such issues lead towards to the design of a new language, rather than relying on an already existing.
