I'm not the C standard.

My bad.

Interesting, as people could say that about you as well.

Some people here like to drag every discussion, every topic, into the 
realm of the C Standard. And a few like to seize on the slightest misuse 
of a term which has a specific meaning in C standard, even though that 
has no practical bearing on the discussion

But what about terms that do not appear in the C Standard?

Since it doesn't use 'implicit cast', presumably I can give that any 
meaning I like, including meaning 'implicit type conversion'. 'cast' is 
shorter to write than 'conversion' or 'coercion', and adds variety to 
sentences.

I notice that no one picked on the casual use of terms I found in the 
N1570 standard, or just waved them aside:

  * Using 'explicit cast'  (which implies 'implicit cast') (6.5.4p3)

  * Using 'type casts' (redundant 'type') (H.2.4P1)

  * Using ' ... conversions (casts) ...' where, if 'conversions' can
    include implicit ones, would imply implicit casts too (H.2.4p4/5)
