Hello; assuming you are a student, and have a couple years before getting hired becomes paramount, I'd recommend becoming facile with Julia and Python, separately. Your intuition about Julia's horizon is very good, and right. And looking two years out, there will be much more 'want' than

I am working on a module that uses bounded intervals. It would be great if the result were easy to use with other's packaged floating-point based or Real derived types. They work like stretchy Float64s, and support arith, exp, log, [a]trig[h], and cdf+pdf+quantile for univariate continuous

ErrorFreeArith.jl offers error-free transformations not (yet?) included in the ErrorFreeTransforms package by dsiem. These operations convey the usual arithmetic result accompanied by a residual value that is usually lost to rounding. This gives

One reason to stay with MIT License is that it has been in wide use for some time. The UPL is newer, and in these matters, there is quite a bit of import in subtle wording; experience clarifies. If you, or someone else wants to make the UPL rights available, just say e.g. (I am not a lawyer)
