| If we're going to extend the read syntax, I'd prefer the scsh variant:
| 
|   #</some funny \\ weird string\/
| 
| In scsh, one can also say
| 
|   #<<END
|    A line-delimited here-string!
|   END

I should have mentioned that, since I added it to the port of scsh
recently:

guile> (load-from-path "scsh/init")
guile> #</some funny \\ weird string\/
"some funny \\\\ weird string\\"

but:

guile> #<%any delimiter %% will do %
"any delimiter "
ERROR: In expression %:
ERROR: Unbound variable: %
ABORT: (misc-error)
ERROR: In expression will:
ERROR: Unbound variable: will
ABORT: (misc-error)
#<primitive-macro! do>
ERROR: In expression %:
ERROR: Unbound variable: %
ABORT: (misc-error)

If it's worth adding to guile-core, then an independent implementation
is likely to be needed since the scsh code is legally incompatible.
