> A common expression like {{(true) ? x : abs(1)}} throws a parsing exception.
> The workaround is to add parentheses around the right hand side {{(true) ? x : (abs(1))}} .
> The actual cause is that the grammar can not disambiguate between a correct ternary expression that uses a function call as right choice and one that uses a namespace function call as left choice {{x : abs(1)}} and misses the right hand choice, that latter case raising an exception.
