PROCEDURE Set(c: M3Context.T; cl: Closure) RAISES {};
Compute the 'depends-on' relation for all the units in 'c', which
then defines the initialisation order of the modules in a program.
cl.callback is called for each unit in the context. cl.context is set
to c before any callbacks. cl.callback should return TRUE if 'm' uses 'i'.
'Default' returns a default closure whose callback returns TRUE if 'm'
uses 'i', as defined in section 5.4 of the report.
However, since it is the use of another module from the initialisation
code of a module that is really significant, a clever client can do better.
