So you always inline the first call to a word?  Or do you have a kind
of delayed compilation so that you might see additional calls before
taking the decision?

Torture test:

: foo ( n -- addr )
  a really, really big word
  or maybe one that itself calls a bunch of other words for the first time
;

: bar ( -- x )
  1 foo @ ;

bar .

: flip ( -- addr )
 2 bar @ bar @ bar ;

: flop ( -- )
 5 3 bar @ bar ! ;
