Ok, I wish to create a standard timing system so that I can measure ~how long each function takes to execute.I wish to be able to place at the start of a function version(Time) mixin TimeExecution("funcName"); mixin template TimeExecution(T) if(isSomeString!T) { import std.stdio, std.datetime, std.conv; auto sw = StopWatch(AutoStart.yes); // Error: Declaration expected, not '(' scope(exit) writeln(T, ": ", to!Duration(sw.peek)); } Why do I receive the Error when the scope statement is included? Is this an error, or what is the rationale behind the decision? Thank you.
It appears that you cannot mixin *any* statement with scope([exit,success,etc]) in it.
I have been rereading my copy of TDPL, and it states that mixin statements must be valid D code, and there can be multiple 'scope()' statements.
Since "scope(exit) writeln();" is valid D code, and refuses to compile in a mixin, I assume that this is a bug.
I've been digging through the bug tracker and I cannot find a duplicate bug, so if someone can confirm that this is a bug, I'll create a report.
