Hm.

Consider your argument about "reference" being possible to confuse with "pass by 
reference" in the light of "pass by name", used by Algol, <url: 
http://en.wikipedia.org/wiki/Jensen%27s_Device>.

Oops, to consistently remove all possible ambiguity the term "name" can't be 
used about formal arguments.

I think, even though "pass by name" is much less well known than "pass by 
reference", this indicates that it's not practically possible to remove all 
possible ambiguity.

I think some Common Sense(TM) must in any case be assumed, and applied.
