consider this:

module report;

// output an error message on stderr
void error(A...)(string fmt, A args)
{
	import colorize : fg, color, cwriteln, cwritefln, cwrite;
	stderr.cwrite("error: ".color(fg.yellow));
	cwritefln(fmt.color(fg.yellow), args);
}

void warning(A...)(string fmt, A args)
{
	import colorize : fg, color, cwriteln, cwritefln, cwrite;
	cwrite("warning: ".color(fg.blue));
	cwritefln(fmt.color(fg.blue), args);
}

then

class C
{

	void error(A...)(string fmt, A args)
	{
		import report : error;
		reportedAnyError = true;
		error(fmt, args);
	}
	alias warning = report.warning;
}


I got this:

Error: undefined identifier report.warning

but this works:

	void warning(A...)(string fmt, A args)
	{
		import report : warning;
		warning(fmt, args);
	}

why alias cannot find my symbol there?

If that really is the code, you're forgetting to import report in that 
scope. Otherwise, that kind of alias works at least in this simple case:

void foo(A...)(A a) {
     import std.stdio;
     writeln(a);
}

alias bar = foo;

void main() {
     bar(42, "hello");
}
