Adding a function declaration to expression.hh causes many recompilations. Reduce that by: - moving some restrictions-related definitions to the existing expr/restrictions.hh - moving evaluation related names to a new header expr/evaluate.hh - move utilities to a new header expr/expr-utilities.hh expression.hh contains only expression definitions and the most basic and common helpers, like printing.
