Hello,
Custom constructors defined via C: sometimes seem clumsy. Maybe using 'make'
could help in some cases. Here's the piece constructor in
tetris-piece.factor :
C: piece ( tetromino -- piece )
[ set-delegate ] keep
0 over set-piece-rotation
{ 0 0 } over set-piece-location ;
It's a one-liner with make:
C: piece ( tetromino -- piece ) drop
[ piece , , 0 , { 0 0 } , ] { } make >tuple ;
