That's why we have immutable variables. They force you to think what to put in the variables. A lot of cases like the one above would be solved if if-then-else was an functional expression instead of a void returning statement. C/C++/D has the ternary ?: but the syntax is obfuscated.Object p = if (m) { ... foo; } else { ... bar; } instead of Object p; if (m) { ... p = foo; } else { ... p = bar; } There are even cases where the former can be const. The latter one has to be mutable in any case.
Not related to this but i have to share. Try compiling this in C/C++. int i = i + 5; // something like this. This compiles with no warning, no error, nothing... I have absolutely no idea how this thing survived so long. -- Using Opera's revolutionary email client: http://www.opera.com/mail/
