It drives you nuts. At least it does so in pike, which is a (discretionary, it has a type "mixed") statically typed language and overloads the arithmetic operators for string types. See http://pike.roxen.com/documentation/tutorial/tutorial_5.html#5.1 for the full details. Here is the relevant excerpt: operands: string + string return type: string In this case, any int or float is first converted to a string. Then the two strings are concatenated and the resulting string is returned. operands: string - string return type: string A copy of the left string with all occurrences of the right string removed. operands: array(string) * string return type: string All the strings in the array are concatenated with the string on the right in between each string. Example: ({"foo","bar"})*"-" will return "foo-bar". operands: string / string return type: array(string) In symmetry with the multiplication operator, the division operator can split a string into pieces. The right string will be split at every occurrence of the right string and an array containing the results will be returned. Example: "foo-bar"/"-" will return ({"foo","bar"}) Now if you would kindly look up the overloaded operator definitions for arrays and hashes (called mappings in pike) and after that retire to a secluded place _before_ you vomit?
