ansi c conversion rules of two arithmetic types (if called on other types, it just returns the first type; hence the pattern if cocerce(x,y) return converse(x,y) should yield the default behavior )

default is int. if either operand has a higher priority, it is preferred over int

are both types char but with different signage?

we can report as a warning if both types are number, but they are not the same width or signed
normalize types for internal comparison in coerce (do not return this to the outside)

* function -> pointer to function
* pointer to pointer to function -> pointer to function
* remove any CObj within the type
* regard arrays as pointers
* pointer to ignore equals ignore
* CVoid in function parameters is removed
promotion is what happens internally during conversion
