   Any comment?

For this particular case, you can use instead ‘getcwd’, which
is builtin.  See also ‘shell-command->string’ and friends:

Tangentially, Guile 1.4.x has "guile-tools gxsed", a sed
implementation in Scheme:

 http://www.gnuvola.org/software/guile/doc/guile_002dtools-gxsed.html

It needs some work to be compatible w/ Guile 1.8 and 2.0
(i.e., to use 2-arg ‘eval’), but the core transform is sound.
IIRC it PASSed around 60% of the GNU sed 4.2 "make check".

For Emacsoid in-process editing, see also module (ttn-do mogrify),
also in ttn-do.  I (and my daemons) use it every day w/ Guile 1.8.
