Include variable type in popup

It would be great to include the variable type in the pop-up which appears when the ctrl key is held down and the cursor moved on top of a variable. This would lead to similar behaviour to what happens for C/C++ (see attached figure for a comparison, with C on the LHS and Fortran on the RHS).

At the moment finding out the type of a variable is impossible to do on the fly and requires to either jump to declaration and back or open the "quick definition" panel, which is a bit awkward to use for such a simple task.
