object ELPI

implementation of the syntax of the ELPI system by Claudio Sacerdoti Coen and others

In concrete syntax, clauses are written with inverted implication and implicit quantification of upper case variables.

Upper-case variables are instantiable while lower-case ones are not. (In queries: existential; in assumptions: universal)
