Is there a way of getting the line number of the current AST node. All
I seem to be able to get is the line number of the next AST node using
the following:


Maybe by "current" I mean previous. Basically, if an error occurs
during a symbol table look up I want access to the node that caused
that error, not the node after it.

This would be very useful for error reporting.
