238 Note about comparing lists: Two lists are considered equal if they have the
239 same length and all items compare equal, as with using "==". There is one
240 exception: When comparing a number with a string and the string contains extra
241 characters beside the number they are not equal. Example: >
242 echo 4 == "4x"
243 < 1 >
244 echo [4] == ["4x"]
245 < 0
246
247 This is to fix the odd behavior of == that can't be changed for backward
248 compatibility reasons.
