But I habitually do it both ways.

What about with a gui?  The gui way of doing this
would be to click on the line with the opening curly-brace.

Sure, I appreciate that -- just speaking up for the other viewpoint.

Don't forget my argument about prologue initializations.
Sometimes those involve function calls.  A user might very

BEFORE others, so he could step into them.

Especially in C++, where some of them would be constructors.
