is_genvar

Term.is_genvar : term -> bool

Tells if a variable has been built by invoking genvar.

is_genvar v attempts to tell if v has been created by a call to genvar.

Failure

Never fails.

Example

> is_genvar (genvar bool);
val it = true: bool

> is_genvar (mk_var ("%%genvar%%3",bool));
val it = true: bool

Comments

As the second example shows, it is possible to fool is_genvar. However, it is useful for derived proof tools which use it as part of their internal operations.
