At what point did anyone claim it was a new idea? The blog post cites prior art in the very first paragraph. Not in a footnote—in the main text. The top post here cites several other languages with a similar model. This entire thread reads like a bunch of dudes who are really dying to "well, actually" someone.

Because it isn’t true. Haskell is an example of why it isn’t true.

[StefanKarpinski]

It's extremely debatable that Haskell is compute-oriented. I know that Haskell people like to talk about doing numerical computing in Haskell, but in reality it does not seem to be a thing. No one has ever used Haskell to implement large scale scientific computations on supercomputers, for example.

This particular example appears to be an implementation of a 'Computer algebra system', which seems to be a type of symbolic computing rather than numerical computing.
