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.
It is not a bug. Use a string mixin.
Well, dangit. Thanks!
