gapt.proofs.gaptic.tactics.ExistsLeftTactic
case class ExistsLeftTactic(mode: TacticApplyMode = ..., eigenVariable: Option[Var] = ...) extends StrongQuantTactic

Decomposes an existential quantifier in the antecedent of a goal.

Value parameters

eigenVariable

If Some(v), the rule will attempt to use v as the eigenvariable. Otherwise it will automatically pick one.

mode
