Erlang/OTP does medium difficulty things, i.e. very large applications with good fault tolerance and QoS, really well.

But it's a very different niche. Perl and Ruby scale to mid sized applications quite well, but above that fault tolerance and QoS become hard.

I think with languages like Perl, Ruby and Python you just need a static, compiled language to migrate to at a certain scale, preferably with similar features. Kotlin and Scala seem to be currently the best options for Ruby, Python and OO Perl. For procedural Perl maybe Golang.

Rust gets large amounts of inspiration from perl so don't forget that one.

Wikipedia quotes Ruby as an influence, but not Perl, citing this source: https://doc.rust-lang.org/reference/influences.html

Still, Perl might have influenced Rust via Ruby. Otherwise, do you have a reference for Perl's direct influence on Rust?

Python has a number of similar, static, compiled languages that are embeddable in Python code (notably Cython and taichi).
