OCL21 — There is no simple way to invoke an "if then else" on a collection

Suggestion: Define an "alt" collection function, with a specific notation, as in:
mylist->alt(iterator | condition? thenExp, elseExp)
The expression elseExp is not evaluated if condition returns true

It is not true that there is no way:
mylist->collect(iterator | if condition then thenExp else elseExp endif)
which has two more tokens than the suggestion but avoids introducing a "?" syntax irregularity.
Disposition: Closed, no change
