Functions
template<typename StmtOrExpr , typename T >
bool	Halide::Internal::stmt_or_expr_uses_vars (const StmtOrExpr &e, const Scope< T > &v, const Scope< Expr > &s=Scope< Expr >::empty_scope())
	Test if a statement or expression references or defines any of the variables in a scope, additionally considering variables bound to Expr's in the scope provided in the final argument.
template<typename StmtOrExpr >
bool	Halide::Internal::stmt_or_expr_uses_var (const StmtOrExpr &e, const std::string &v, const Scope< Expr > &s=Scope< Expr >::empty_scope())
	Test if a statement or expression references or defines the given variable, additionally considering variables bound to Expr's in the scope provided in the final argument.
bool	Halide::Internal::expr_uses_var (const Expr &e, const std::string &v, const Scope< Expr > &s=Scope< Expr >::empty_scope())
	Test if an expression references or defines the given variable, additionally considering variables bound to Expr's in the scope provided in the final argument.
bool	Halide::Internal::stmt_uses_var (const Stmt &stmt, const std::string &v, const Scope< Expr > &s=Scope< Expr >::empty_scope())
	Test if a statement references or defines the given variable, additionally considering variables bound to Expr's in the scope provided in the final argument.
template<typename T >
