For me, the small syntax extension is a convenience when working
with longer definitions. A bit contrived (:= synonym for TO):

BTW, why do you prefer the special syntax `<: ... ;>`
over an extension to the existing words `:` and `;`

In this approach the word `:` knows that it's a nested definition and
behaves accordingly.

 Or it has not even know it, if [ is smart enough to compile a jump to
after ].

This can be tricky because the following should work:
   create foo [ 123 , ] [ 456 ,
   : bar  [ ' foo compile, 123 lit, ] ;
