Axiom H : a
fix(frontends/lean/parser): parse_type method The parser had a nasty ambiguity. For example, f Type 1 had two possible interpretations (f (Type) (1)) or (f (Type 1)) To fix this issue, whenever we want to specify a particular universe, we have to precede 'Type' with a parenthesis. Examples: (Type 1) (Type U) (Type M + 1) Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2013-12-19 23:15:32 +00:00			`Definition B : Type := Bool`
