anyone tried to compile it?

I'm getting this when trying to run it:

  $ cc main.c
  ... lots of warnings ...

  $ ./a.out 
  1
  
  1 
  2*2
  Segmentation fault (core dumped)

It doesn’t have *. What it has is listed in the declaration starting with “C vt[]”. Those are the names of verbs and the following lines give the function pointers for their monadic and dyadic uses.

It worked fine for me when I was careful to stay within what it actually supported, bearing in mind it’s a fast and rough implementation not something for production use.

It will run but it requires 32-bit pointers and 32-bit integers. And error handling is limited.
