I’ve had this recently. Was writing Python but missed the ease of concurrent functional programming. Used F# but missed type classes. Used Haskell but missed dependant types. Use Idris but miss the build environment of Python.
Yes, once you learn enough languages I feel like you just find yourself constantly wishing you had aspects of another language, pretty much regardless of what language you're using. Sometimes its directly related to the language, sometimes its something like the ecosystem surrounding it.
This is why I'm wary of "right tool for the job" when it comes to languages. In my experience usually there isn't a singular obvious right language. Maybe one is 35% right, another is 38% right, and the golden ticket language is actually just 45% right. And sometimes you won't really know until you're halfway through the project.
If you wanted a 100% singular obvious correct language, you would have to make a custom language with traits from a dozen different ones. But in the real world, the differences between languages you can actually choose from end up being not that large.
I think of languages as a multi-dimensional tree, with branches extending in different directions. I think that the trick is to figure out what the yak-shaving aspects of the project are going to be (which you can think of as a vector), and picking the language that goes the furthest in the direction of that vector (and thereby does the most to minimize the yak-shaving). This requires that you be able to fairly accurately determine what the yak-shaving will be up front (which can be problematic).
