Well, yes and no. Many languages simply do not pass 'GUI criteria' and, imho,
Racket is very much deprived of its glory by providing first class GUI option
for all those not so enamored with JS/browser stuff.
Some languages were simply excluded without even slight consideration like {C,
C++, Java}, some are uninspiring (Go) or have (too) strange syntax etc.

Yes, it's supposed to crunch the numbers, but I plan to use 3rd party C library
for that and then just provide higher-level bindings to if from the host
language and write custom libraries which use functions from the C lib on top
of that.

No, it is supposed to be open-source hobby project, so there must be some fun
doing it. I also would like to avoid "2 language problem" in regard to GUI.

It also seems that Julia does not want to be too 'general programming
language'. :-)

Ohh, that's very helpful. Thank you very much for this insight.

Two questions in regard:
1) is there a plan to fill the gap with the 'missing' widgets in the
foreseeable future? (Iirc, someone once mentioned to me 'tree widget' which is
not included out of the box.)
2) how difficult is, in general, to add new widgets?

Julia seems to me as interesting language - in the past I was also looking at
Dylan - and numeric performance is not the main reason behind my interest, but
e.g. Python is certainly too slow as proved by some people trying to
write similar apps and abandoning it to eventually go e.g C++.

Based on what I read, Typed Racket is something I want to explore.

Thank you for shedding the light on this issues.
