According to the Kernel::Integer docs, ArgumentError should be raised if the argument is a String and doesn't conform with numerical representation. However, it appears that Kernel::Integer does not raise ArgumentError when a string contains leading or trailing whitespace.

Ruby Version: ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-darwin18]

Reproduce Steps:

Integer(" 1")
Integer("1 ")

Actual Results:
both parse to a valid Integer, 1, no exception is raised.

Expected Results:
both should raise ArgumentError because they contain non-numerical characters
