I find that stderr is my friend! I can execute this statement from meta-x: (define squarel (lambda (x) (* x x)))
(of course it doesn't work to call this from texmacs cos it gets passed a tree) but when I try and embed that in an extern lambda within the editor like this: <extern|(lambda () (define squarel (lambda (x) (* x x))))> it prints as <syntax-error|memoization|~A ~S.|?|?> and stderr shows: <unnamed port>: In procedure memoization in expression ((lambda () #)): <unnamed port>: Missing body expression in ((define squarel (lambda (x) (* x x)))). So what's going on there? Sam
