Yes. Those work by tying python to pieces written in a more performant language.

And Perl has PDL. Not aware of anything for Tcl beyond math::statistics, but I think it waned in popularity way before the ML bubble started inflating.

But in my experience, the strategy for Tcl is the inverse of Python when it comes to domming/subbing with your "partner language". You _extend_ python, you _embed_ Tcl.

At least in the areas where Tcl still survives. It lost long ago against the P-languages, but still faces Lua rather bravely in the enterprise/engineering sector.
