[Texmacs-dev] define in a lambda

[Sam Liddicott]

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?
