If you use a SourceReader as the input to evalInput, you should be
able to just use the values of line, column, and sourceFile, which are
public fields of SourceReader.  They should be set to the file
position *after* reading the error causing data.

You can do the same thing but read the expression yourself (using the
dynamic environment's parser), taking note of the line/column data
before reading so that you have the start of the offending characters
as well.  The dynamic environment is found in the "dynenv" field of an
Interpreter, also public.

Of course, all of this is unsupported. :)
