auto&& vec = some_expression_that_may_be_rvalue_or_lvalue;
auto i = std::begin(vec);
(*i)++;
This code will compile just fine regardless of the initializer expression. The alt...
What are the most common naming conventions in C?
...n structs: classic C style: gtk_widget_show(), tracking_order_process().
Pointers: nothing fancy here:
GtkWidget *foo, TrackingOrder *bar.
Global variables: just don't use global variables. They are evil.
Functions that are there, but

I recommend reading the following points from the C++ FAQ Lite:
Why can’t I separate the definition of my templates class from its declaration and put it inside a .cpp file?
How can I avoid linker errors with my template functions?
How does the C++ keyword...
How can I check if my python object is a number? [duplicate]

So as you can see, there's no way to do that for static methods.
And another thing just dawned on me: what would really be the point of being able to add static methods ...
