I agree with the first missing feature as you state; I just don't know how much value-add those features actually add in real world apps - often people use them in weird and unintitutive ways as well. F# has other features that other languages don't have as well. I find the workflow syntax eliminates some of the need for the first; and I find I can write functions that work with most numeric types at least a lot more so than C#/Java/etc. As a simple example the in-built F# library comes with functions that work on most number types (e.g SumBy works with anything that supports (+) including my own types). Sure there might be advanced examples that I wish I could do but they don't come often. I do find F# more concise, generally less "smart" and more explicit than Scala code which I think is a good thing. I've seen some funky Scala code in the past. Ease of code/learning/etc, and a maintainable codebase at least for me trumps features most of the time.
