I expect to revamp the property expression language in 5.1 (or perhaps
5.2, depending on priorities) to support this, almost. Unless I get
very clever, I don't think we'll see ${var:index} allowed ... you'll
have to use a real property, not a var: psuedo-property, but then it
will look lke:
t:source="promotedCols(index)"
I also expect to add some ternary operator (test ? expr1 : expr2), a
"smart" dereference ("[ expr ]" that can be applied to arrays, Lists
and Maps), and maybe some simple filtering / projection operators,
along with method invocation.
