class RuboCop::Cop::Style::NestedParenthesizedCalls
Checks for unparenthesized method calls in the argument list of a parenthesized method call. ‘be`, `be_a`, `be_an`, `be_between`, `be_falsey`, `be_kind_of`, `be_instance_of`, `be_truthy`, `be_within`, `eq`, `eql`, `end_with`, `include`, `match`, `raise_error`, `respond_to`, and `start_with` methods are allowed by default. These are customizable with `AllowedMethods` option.
@example
# good method1(method2(arg)) # bad method1(method2 arg)
@example AllowedMethods: [foo]
# good method1(foo arg)
