• Why is T() = T() allowed in C++?

  - by Rimo

  I believe the expression T() creates an rvalue (by the Standard) However the following code compiles (at least on gcc4.0) class T {... }; int main() { T() = T(); } I know technically this is possible because member functions can be invoked on temporaries and the above is just invoking the operator= on the r-value temporary created from T(). But conceptually this is like assigning a new value to an r-value. Is there a good reason why this is allowed?

  I am trying to check if a html document includes script tags that are not empty using regular expressions. The regular expression should match any script tag with a content other than whitespaces or linebreaks.

Even for an empty class which simply extends an NSObject has many options, most of which seem completely useless. What is the reason for having so many auto-complete options, or can they be "tamed" in the preferences?
