The VS debugger can call functions in the watch window, but that needs appropriate debug information. Unfortunately the full function type info is not generated by dmd.

How's this going? Has there been any progress? This would be super handy!! `pure` properties are overwhelmingly common.

I remember I tried allowing calls within the expression evaluator (and fixed the parsing) but actually executing it didn't work so easily. So no support yet.

The concord plugin in the latest build on https://ci.appveyor.com/project/rainers/visuald allows calling simple free functions, i.e. no arguments. They might have to be given fully qualified, e.g. "TestApp.testcall()".

No member functions so far...

It can call them... even if they mutate global state?

Yes, you can also do this in C++. It's necessary to click the "Try Again" icon, though, to not reevaluate it in the watch window with every step. I think this can be done, too.

For properties execution should be automatic, but I don't think the debug info contains info about strong purity. We might have to extract that info from the mangling :-/

This is going to be so amazing if it works!

You can now call function and delegates without arguments in the watch window, i.e. this includes member functions. You'll still have to add "()" even for properties.

Okay, that's awesome!

Seems to work well.
So for const pure properties (or methods that look like properties) where it's
safe to call them without mutating, is it possible to automatically populate
the struct/class with phony members for the property getters?
Ideally they would have a different little icon than data members (like C# does
with its properties).
