OK, I see now. I had changed the code to perform the same with integers 
and yes, it also does not report a warning only a hint which is enought 
to me.

I'm quite sure that the library that starts this thread does not show a 
hint, so maybe in some situations it could fail. I'll try to reproduce 
it in a small code (if there is a problem, of course), meanwhile 
everything seems to work as expected.

Thank you for your help.
