That depends on what selector they're using. For `selection(node(ExprId))`, yes 
I think that `expression(ExprId)` is going to be better in most cases. But, for 
other selectors, no.  So, I'm not sure that the cross-reference will be 
generally useful.  WDYT?

Also, it occurs to me that we have an asymmetry for statements and expressions. 
Getting the source of a statement is
`selection(statement(Id))` versus `expression(Id)` for expressions. However, in 
the context of `cat`, which takes `RangeSelector` directly, they look the same, 
because `selection` isn't needed.
