[sqlite] error in documentation of SELECT?

[Mitchell L Model]

I may be misreading the select-core diagram on 
http://www.sqlite.org/lang_select.html  but it appears that the down-arrow that 
would allow a query without a FROM clause should not be there. Is it really 
possible to have a SELECT with no FROM? If so, could someone provide an 
example; if not, would someone maintaining the documentation make a note of 
this? Thank you.
