I just decided to learn the basics of Haskell and this is quite fascinating (I encourage anybody to discover it).
Now the more I read about Haskell the more I feel like RPL has some familiarities though it doesn't belong to the family of functional programming languages. I find Haskell interesting for some math applications, and the syntax is quite light so I was wondering if there had ever been some thoughts about having Haskell on a calculator?
You might like
Joy which I consider a mix of Haskell and Forth.
The
nutstudio (HP-41 calculator emulator and tools) could be of interest as well.

Haskell is very interesting....
Not totally haskell but I use a lot the "Gofer Library" on my HP50G :

Read me
An excellent and must-have library !
I think that if you like Haskell, you will like this library.
I did consider the possibility of using something like Haskell and an arbitrary precision numeric library in a calculator to guarantee results to a specific number of significant digits. The lazy evaluation is a bonus here, the unlimited memory requirements a set back. Still, it would be an interesting project.

One nice feature of Haskell is that it generates C code. So if one were, hypothetically speaking, intending to produce an entirely new firmware for a calculator like the 50G, then writing a new RPL in Haskell rather than directly in C would result in much more rapid development times, with rather fewer bugs and more easily automated testing.
So don't port Haskell to the calc, but use it to develop a new calc. As I suggested in another thread previously, FreeRTOS provides a nice OS base and any new RPL implementation can run as an app on top of it.
