Preston Carman commented on VXQUERY-158:
----------------------------------------
Each expression is handle at runtime. If expressions are nested, the inner most
expression is evaluated first. The results of this expression are used to
evaluate the next inner most expression, and so on. When writing the runtime
function, each argument is considered to be already evaluated into a constant.
> Can not read/evaluate { } in queries
