Stdout cannot print large numbers of objects using varargs

Description

Stdout(1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1);

The above line compiles, but it segfaults at runtime. Looking at the source, tango/io/Print.d:143, there are default format strings for anywhere from 1 to 12 objects, but none for greater than twelve.

To minimize heap activity, I suggest keeping the current system with premade format strings, then, if there are too many arguments, use a recursive method to assemble a format string. It will be relatively rare to have that many arguments, so this method will rarely be called.

hrm, it should assert instead, but yeah .... Stdout.format() also has a limitation, but it's something like 64 arguments instead.

Thanks; I'll look into it.
