Yes; IMHO we are at about the point to start doing this; as some Forth 
systems have converted to a smart compile, - an approach we didn't use 
before.

Gforth's development version now has a smart compile,, too, and the syntax 
to use it is pretty similar to your comp:, so well, I should better just 
call it comp: to avoid unnecessary discussions about how it's named.  The 
semantics is identical, it gets an xt.  You can have comp: (or compile> as 
it is called now) also inside a definition, which then, like DOES>, 
overrides the compile,-method of the last definition.

This however requires that we also need to "set the words right", because 
the execution and compilation semantics as written in the standard now are 
not clear enough for this approach.  Anton at least opposes the idea that 
COMPILE, is for the compilation semantics, because now it a) isn't, and b) 
is not defined that way.

BTW: I'm *not* happy with using something like compile>/comp: inside a 
definition.  Like DOES>, it tears the definition into two parts, ending the 
first, and starting a second one, and thus means that you can't go on and 
adding e.g. a DOES>, or a TO-behavior (which we don't need to discuss here, 
but is available in Gforth-current).  Quotations are more handy for that, 
the "assing an xt to the compile, method of the last defined definition" in 
Gforth it is now !COMPILE, (preliminary), in VFX ist is SET-COMPILER (and 
there is a GET-COMPILER, which deems to be not very useful - the more 
generic, to get the compiler method of any XT, would be sufficient).
