## Public predicates

### `rule/4`

Clauses for this predicate are automatically generated using term-expansion. The third argument contains the length of Body.

Compilation flags:
`static`
Template:
`rule(Head,Body,Length,Tail)`
Mode and number of proofs:
`rule(?callable,?callable,-,-)` - `zero_or_more`

### `rule/3`

Clauses for this predicate are automatically generated using term-expansion. The third argument denotes the tail of the Body.

Compilation flags:
`static`
Template:
`rule(Head,Body,Tail)`
Mode and number of proofs:
`rule(?callable,?callable,-)` - `zero_or_more`

### `rule/2`

Clauses for this predicate are automatically generated using term-expansion.

Compilation flags:
`static`
Template:
`rule(Head,Body)`
Mode and number of proofs:
`rule(?callable,-list(callable))` - `zero_or_more`

### `bench_goal/1`

Table of benchmark goals. They are used from shell.lgt to make benchmarking easier.

Compilation flags:
`static`
Template:
`bench_goal(Goal)`
Mode and number of proofs:
`bench_goal(?callable)` - `zero_or_more`
