Ruby – source code – coding style

Looking through the Ruby code it has the following for proc_arity:

static VALUE

proc_arity(VALUE self)


    int arity = rb_proc_arity(self);

    return INT2FIX(arity);


Interestingly, `static VALUE` is on a separate line – i.e. instead of something like this: `static VALUE proc_arity(VALUE self)`

because it helps grep the function definition. E.g. 

$ grep -n ‘^proc_arity’ *.c

or using vim:
