So you either add a type signature, or turn off the warning.  What's the
problem?  

I suspect you're saying that you don't want a warning by default, and
you don't want the langage to recommend that compilers issue a warning
by default, right?  If so, your objection is duly noted and I'll add the
point to the wiki.
