hashmark in symbols

[Andreas Reuleaux]

Hi,

in common lisp I get e.g.

--8<---------------cut here---------------start------------->8---
* (format nil "~a" '\#444)
"#444"
--8<---------------cut here---------------end--------------->8---

(assuming #444 is a css color - that is my use case anyway -
and thus likewise for any other color)

Now, apparently in Guile this is not the case:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> (format #f "~a" '\#444)
$158 = "#{\\#444}#"
--8<---------------cut here---------------end--------------->8---

And likewise

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> (symbol->string '\#444)
$159 = "\\#444"
--8<---------------cut here---------------end--------------->8---


Now I am tempted to case split (after (symbol->string ...) as above):

  if the resulting string starts with \\# then cut off the \\ part
  otherwise ...

but this seems overly complicated!? And is not really what I want! Is
there any other (readable) way to specify the hashmark in a symbol
(assuming \hashmark here, but this is wrong of course), so that

--8<---------------cut here---------------start------------->8---
(symbol->string '\hashmark444)
--8<---------------cut here---------------end--------------->8---

just works: results in "#444" (not "\\#444") ?

PS: I am experimenting with #\x0023, like so

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> #\x0023
$181 = #\#
--8<---------------cut here---------------end--------------->8---

but I still have no clue, how to write a simple symbol, that when
translated to a string, results in "#444".


Thanks in advance,
