What do you think about Julia?
Nim could also play a significant role because its syntax is similar to Python, and because NumPy is a Python API which is very prominent among scientists. However someone has yet to write a Nim library similar to NumPy.
Nim has the advantage of zero overhead to C, and it compiles to C which makes Nim an interesting option for super computing.
Untrue. Nim requires the use of a garbage collector.
# Because Nim compiles to C, FFI is easy:
proc strcmp(a, b: cstring): cint {.importc: "strcmp", nodecl.}
let cmp = strcmp("C?", "Easy!")
