One way you might arranging programming languages in a 2D space is with two axes: 1. How much should the language surprise you? 2. When the language does surprise you, should it delight you or horrify you? surprising ^ | | | delight horrify | | | v unsurprising Only a sadist would deliberately design a language for the top right quadrant, but there are many esoteric languages in there. I think most people tacitly ass…

I'm very interested in bottom right langs.

I think my vote goes to ColdFusion.

My favorite feature of Raku: Integer division and decimal literals both return `Rat`, a rational fraction type. Even though everyone knows floats suck, nobody is actually moving away from them except Raku. If you want a float literal you specifically have to use scientific notation.

Welp now I know what "using it in anger" is gonna look like

I found about raku one time I had an assignment for college where I needed to create a parser. I found raku's grammar features really interesting and used it for my project, it felt almost like cheating since it did pretty much every thing for me (actually it was probably just cheating but it was still fun).

That’s exactly what you want in a language. It should always feel like cheating!

Also debuggers. Give RR a try some time :)

It's actually an awful misfeature, because those Rats will automatically turn into floats when the rational representation gets too big:

  > WHAT 1/10
  (Rat)
  > WHAT 1/100000000000000000000
  (Num)
(There is FatRat, which does not so 'promote', but it is not the default.)

I'm not sure what I think about that. I know when to use decimal/rational types vs floats, but my own Python code has a whole lot more float() calls than Decimal()s. Floats are almost always what I want unless I'm directly working with money.

Scheme’s numeric tower has a handled exact expressions with exact representations correctly for decades, so I guess its true that is not “moving away from” unnecessary and error-prone use of inexact floats where not explicitly requested, but only because it was never there to move away from.

Maybe there's some way to extend the compiler to use OEIS. Is there a "liboeis" that lets you download and interact with the OEIS database offline?
