 * 'T'          double
 *              user mode accepts an optional ms, us, ns suffix,
 *              which divides the value by 1e3, 1e6, 1e9, respectively
 * '/'          optional gdb-like print format (like "/10x")
 *
 * '?'          optional type (for all types, except '/')
 * '.'          other form of optional type (for 'i' and 'l')
