Tactic Failure message (level ‘num’)
Tactic generated a subgoal identical to the original goal. This happens if ‘term’ does not occur in the goal
Terms do not have convertible types
The command has not failed!
The conclusion is not a substitutive equation
The conclusion of ‘type’ is not valid; it must be built from ‘ident’
The constructor ‘ident’ expects ‘num’ arguments

The reference is not unfoldable
The reference ‘qualid’ was not found in the current environment

The term ‘term’ has type ‘type’ while it is expected to have type ‘type’'
The variable ‘ident’ is already defined
