Functions

func DupSubExpr

func DupSubExpr(m dsl.Matcher)

Suppose that we want to report the duplicated left and right operands of binary operations.

But if the operand has some side effects, this rule can cause false positives: `f() && f()` can make sense (although it's not the best piece of code).

This is where *filters* come to the rescue.

func RangeExprVal

func RangeExprVal(m dsl.Matcher)

func StringsSimplify

func StringsSimplify(m dsl.Matcher)
