It's not that painful but it would be nice to be able to compare strings and just receive a warning about the performance issue, however we could see this implemented in the OpenSource version of Delphi, Lazarus IDE and the FreePascal compiler which seems to have a lot of interesting features including some level of precompiler macros, operator overloading, CrossPlatform support and many more i'm not sure how generics work in FPC right now but they should be supported soon. On the IDE side Delphi still feels better but maybe things will change in the not so distant future.
