[Interest] CLion to replace QtCreator?

I don't know what I'm doing wrong but the new compile-time-checked syntax is auto-completed by my Qt Creator (that came with Qt 5.5.1) as well :) and you're a bit blunt on not recommending the older syntax. Apparently you haven't spent enough time with QML.

It only works with the old, Qt4 string/macro-based syntax (using the 
SLOT and SIGNAL macros.) Which is totally unsafe and I don't use it 
anymore (I wouldn't even recommend it to anyone.) The new syntax, which 
is statically checked (compile time) and thus type-safe, even though 
it's the recommended one by Qt, is not supported in Creator using the 
clang model. This does not auto-complete:

   connect(this, &MyWidget::mySignal, control, &MyControl::mySlot);

This is not the end of the world, but still it's unpleasant to work with.

The clang code model will get better in the future, I'm sure of it. But 
right now, it's pain all the way down.

The lacking auto-completion might not even be the worst of it. In the 
end, that's "just" a productivity and convenience issue. The lack of 
reliable "find all uses" in the clang model is actually a more serious 
problem, since if you trust it you're left with the false sense of 
security that you caught all the places in your code where a symbol was 
used and made whatever changes you needed to make to fix an issue. But 
it doesn't find all uses. Which is *dangerous*. So I have to do a 
text-based, project-wide search for a string instead to actually get to 
all uses of the symbol and update my code.
