http://d.puremagic.com/issues/show_bug.cgi?id=9632 Summary: Detect Non-Mutating Call Statements to Pure Functions Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: per.nordlow gmail.com --- I believe D has the potential to add yet another cool feature to its suite of compilers, namely the power to disallow non-side-effect calls to pure functions. For example auto s = "a"; toStringz(a); should error just like a == ""; currently errors in DMD as Error: == has no effect in expression (s == "") Such as feature would prevent the programmer from accidentally calling non-muting algorithms when he expects it to have in-place (mutating) semantics which has cost me a lot of debugging hours. Is such a feature on the todo list for DMD?
