Source locations

[Joris van der Hoeven]

Hi,

In the online guile manual, I found that the instruction

        (read-enable 'positions)

should tell guile to remember positions in the source code.

How can I use this information? I would like to be able
to display a filename and a line/column number when
an error is encountered in an embedded guile program.

Best wishes, Joris
