There are quite a few functions which accept as arg INT or RAT.

The current solution is to call evalArgAsT1orT2<INT,RAT>;
in fact there are also several which call evalArgAsT1orT2orT3<INT,RAT,RINGELEM>.

I want to write a function which accepts a list of RAT but which continues to
work if some or all of the list entries are INT. The obvious call evalArgAsListOf<RAT>
does not do what I want -- it complains if there is an INT instead of a RAT.

It seems to me that INT should always be allowed where RAT is expected.
It is less clear to me whether a RAT with denominator 1 should be accepted where an INT is expected.

Ideas? Suggestions? Points to dicuss?
