Equations

• Lean.Compiler.LCNF.UsedLocalDecls = Lean.FVarIdHashSet

def Lean.Compiler.LCNF.collectLocalDeclsType (s : Lean.Compiler.LCNF.UsedLocalDecls) (type : Lean.Expr) : Lean.Compiler.LCNF.UsedLocalDecls

Collect set of (let) free variables in a LCNF value. This code exploits the LCNF property that local declarations do not occur in types.
