Extremely easy interop with native code is the main selling point of guile IMO. You just link in guile as a library and can have C code call scheme code and vice versa. Makes it great for any native program that needs an embedded scripting language (much like Lua). Does Racket support that use-case?

I haven't done FFI with Racket, but https://docs.racket-lang.org/foreign/index.html looks reasonably approachable?

That seems to let you call C functions from Racket, but I don't see how it lets you embed Racket in a C program and call Racket functions from C. So it's at best half a solution, unless I'm missing something.
