Indicate the name of each parameter in function calls

This is a feature request to indicate the name of each parameter in some way in function calls.

CLion has this feature. If there is a function

void fun(int x, int y);

then the function call

fun(2,3);

is displayed as 

fun(x: 2, y: 3);

This is just one way to convey this information. There could be other ways as well (e.g., tooltips, though I would not find those equally convenient).

I include a screenshot from CLion below:

Notice that CLion annotates arguments in function calls in a smart way: only those arguments are annotated where a literal value is passed. Where a variable is passed, ideally the variable name gives enough hints to identify the argument.

I often work with the igraph C library, which has lots of functions with very long argument lists. It is often difficult to identify which argument is which when reading code. CLion makes the code much more readable. I would find a similar feature in Qt Creator extremely useful.
