Personally, I don't think that a special syntax for variable
definition fits well in a stack-based language. I prefer the
PostScript syntax of quoting the word and using the def keyword,

     2 $var def


     { 'hi' print } $foo def

or the reverse, or another quoting character. It could also
replace &foo to push a block onto the stack, since executing the
quoted word would be equivalent to executing its associated
