For _ this should not be too bad: It only has a special meaning in wisp when 
used as the very first character in a line (then the underscore and consecutive 
underscores are treated as whitespace).

For : I am not perfectly sure. I know that typed racket uses it for 
type-declarations¹, so this is a regression. On the other hand this only hurts 
for top-level defines, where it is seldomly needed. I added some details under 
http://draketo.de/proj/wisp/srfi.html#sec-3-2 (disadvantages of wisp).
