Hi

Just because I hit it today i am reporting this, but with low priority. I got into
this small problem [a very small and ridiculous example for the sake of
'demonstration']: the doc says [6.17.7]

	The coding declaration must appear in a scheme comment. It can either be a
	semicolon-initiated comment or a block #! comment. 

if you deposit the 3 attached files somewhere in your guile-load-path, 
chmod a+x test-iso-preceeding-comment

and execute it it's ok. but if you comment (use-modules (test-1)) and uncomment
(use-modules (test-2)) it's not

Cheers,
David
