What's wrong with char C / [char] C ?

(Could also be extended with gforth's et. al. C-like escapes, e.g. 
"[char] \n", but clashes with established use since the 80s, namely that 
CHAR pushes the literal character code of the first character of the 
following word in the source (delimited by BL), which unfortunately has 
been standardized by ANS 94).

Single character constants are commonly not used so frequently that a 
shortcut for them is urgently needed.
