Nim's home page¹ shows a piece of sample code right at the top. Perl6's page² has a few tabs quickly showing some patterns it's good at. Golang³ has a dynamic interpreter prepopulated with a Hello World.
Julia's home page shows a nice feature list and links to docs to deep dive but it doesn't do a good job of selling it.

Lisp languages do take a long time to get used to.
The first impression does leave me thinking that using Julia for different programming domains like distributed internet-facing servers or web services is not something it was built for.
No. Julia is a general purpose language that has so far been mainly focused on scientific and mathematical programming.
It's design is probably least friendly to the real-time programming domain (GC based) but it can apparently be used there as well:
I see an extremely bright future ahead for Julia!
Notice that this function is purposefully sleeping the differential equation solver in order to slow it down to the exact amount to get the simulation back to real-time.
You can see how much extra time is left for that frame at the targeted frame rate, then sleep for that amount of time.
Then you never have to slow down anything else, you can set a maximum amount of cycles per second and you can sleep once per cycle. The faster the CPU, the less power it should use.
So like Python, you have SciPy Pandas etc. but don't have to leave Python when you need to do a bunch of text processing or whatever.
At the same time, calling into other languages (eg C) is super straightforward (disclaimer: last time I checked).
And of course, I should really assist to solve this problem myself. But, I thought to encourage other language experts.
f_2dlinear = (du,u,p,t) -> du.=1.01u
prob = ODEProblem(f_2dlinear,rand(2,2),(0.0,1.0))
