• Simplify_common const_*_expr expr v annot, where the expression expr is known to evaluate to the value v, attempt to produce a more simple expression together with its approximation and the benefit gained by replacing expr with this new expression. This simplification is only performed if expr is known to have no side effects. Otherwise, expr itself is returned, with an appropriate approximation but zero benefit.

• Unbox_free_vars_of_closures When approximations of free variables of closures indicate that they are closures or blocks, rewrite projections from such blocks to new variables (which become free in the closures), with the defining expressions of the projections lifted out of the corresponding sets of closures.
• Unbox_specialised_args When approximations of specialised arguments indicate that they are closures or blocks, add more specialised arguments corresponding to the projections from such blocks (with definitions of such projections lifted out), such that the original specialised arguments may later be eliminated.
• Var_within_closure An identifier, unique across the whole program, that identifies a particular variable within a particular closure. Only Project_var, and not Var, nodes are tagged with these identifiers.
• Variable Variable.t is the equivalent of a non-persistent Ident.t in the Flambda tree. It wraps an Ident.t together with its source compilation_unit. As such, it is unique within a whole program, not just one compilation unit.
