Following the short time thinking there was a regression somewhere wrt to attribute constructors (working on BOO-1078), I think we should get a typo warning for some boo keywords that are used in a precise context. After all C# and other languages do not have such potential typo problem with constructors/destructors (at least) since the syntax requires repeating the type name. Typo would be checked in a method context only (not property etc..) case-insensitively (ie. "def Constructor" would warn) and with +/- 1-letter distance (such as "def IsConstructor" for instance, do not warn). 'Keywords' to be checked: constructor destructor And also (if static): op_Addition op_Subtraction op_Multiply op_Division op_Modulus op_Exponentiation op_Equality op_LessThan op_LessThanOrEqual op_GreaterThan op_GreaterThanOrEqual op_Match op_NotMatch op_Member op_NotMember op_BitwiseOr op_BitwiseAnd
