You could just output your styles into the content output, and use an 
html 5 doctype.

It's also interesting to note that with HTML 5, style tags are 
allowed/appropriate in the content and Valid according to the spec. :-) 
Further, most/all browsers support it (it was only considered bad 
practice due to standards) and as HTML 5 support improves, browsers will 
support the scoped attribute! As for the benifits of enqueing styles, 
perhaps a patch: if enque after head, place in content, else default 
behavior? I don't know too much about the internal workings there.

Tho the solutions involving buffering will still probably be appropriate 
for scripts.
