Embedded scripting languages

What scripting language would you embed to a program? The performance would not be main issue, since the compiled part of the program would worry about that.

The scripting language would call many functions written in C, C++, or whatever lang that can compile C-like functions (so there needs to be some kind of easy to use FFI).

I thought about options here:
- Lua
- Scheme (tinyscheme or whatever)
- Something else?

Now, what would /prog/ use, and why? ("Read SICP" is not a valid answer here)

The authors of the shootout know this very well. That's why they preface their page with this:

Measurement is highly specific -- the time taken for this benchmark task, by this toy program, with this programming language implementation, with these options, on this computer, with these workloads.

Same toy program, same computer, same workload -- but much slower.

Measurement is not prophesy.
