I guess there must be a reason for not matching Lazy constructor, in fact
I see no constructor in the Lazy module. Maybe I am missing something here.

I do not get the idea either, can you be a bit more specific ?
I have more or less the feeling that

match f with
 pattern <= expr expr expr -> bonga

means

match f expr expr expr with
p -> bonga 

Thus I hardly seen your point.
