(Guile-SDL) Feature request: Return integer value for keysym in procedure event:key:keysym:sym

[David Thompson]

event:key:keysym:sym returns a symbol, but it would be nice if there was 
a way to get the actual integer value of the keysym as well.

I'm writing an input module for a game library and I'm wrapping up the 
keycodes into their own enumeration with a  macro like so:

(define-enumeration
  keycode
  (backspace 8)
  (tab 9)
  (clear 12)
  (return 13)
  (pause 19)
  (escape 27)
  (space 32)
  (exclaim 33)
  (quotedbl 34)
  (hash 35)
  (dollar 36)
  (ampersand 38)
  (quote 39)
  (leftparen 40)
  (rightparen 41)
  (asterisk 42)
  (plus 43)
  (comma 44)
  (minus 45)
  (period 46)
  (slash 47)
  (0 48)
  (1 49)
  (2 50)
  (3 51)
  (4 52)
  (5 53)
  (6 54)
  (7 55)
  (8 56)
  (9 57)
  ...)

Unfortunately, this doesn't work because there's no way to get the 
keycode as integer.
I can see how returning a symbol is nice, but it would be also be nice 
to not hide the integer value underneath.

Thoughts?
