Semantic highlighting of parameters

This will make it easier to visually distinguish between the name of a function and its parameters when definining it.

 let somelongname barfoo someotherparam onelast = ....

Here it would be easier to spot that somelongname is the function name, and the rest are parameters.

It will also make it easier to distinguish between local let bindings/values and the parameters from the outside.

Other languages have this distinction (e.g. javascript). Imo it’s even more useful in F# because there’s no symbols ( ) look for.

It would also be useful to have semantic highlight when a function is called. So that when you invoke/call somelongname myparameter yetanotherparameter true, you could easily see that somelongname is being called, and the rest are just passed to it as params.

@drhumlen I’m glad you like it! We’ve decided to not change any defaults with new highlighting capabilities. I also have an option to highlight parameters differently too, but it’s in my custom fcs build and my PR enabling this feature is basically ignored by dsyme. Can’t help it. Also, values of literals are properly shown in tooltips now 😃

I’m actually trying to get this thing done now but I guess it’s kinda hard to do it with parameter as I still can’t really find a “transition” between FSharpValue and FSharpParameter.

Looks kinda like this and I already like it because I can easily spot methods and funcs but it’s still not ideal as I’m quite a fan of having parameters highlited differently too.
