Module qtype 

Source
Expand description

This module provides a list of q types. The motivation to contain them in a module is to tie them up as related items rather than scattered values. Hence user should use these indicators with qtype:: prefix, e.g., qtype::BOOL_LIST.

§Note

In order to facilitate type check without overflow this module defines atom type indicator as well as list type indicators (We don’t need to compeletely mirror the C API).
