Arrays.count fails when used in macros

[tkwiatek]

Description

@:generic methods fails when used in macros

Code examples

Direct use with thx import

using thx.Arrays;
class Test {
	static function main() {
		trace(checkCount());
	}

	macro static function checkCount() {
		final arr = ['a', 'b', 'b', 'c', 'c', 'c', 'd', 'd', 'd', 'd'];
		final count = thx.Arrays.count(arr);
		return haxe.macro.Context.makeExpr(count, haxe.macro.Context.currentPos());
	}
}

fails with:

[ERROR] (unknown position)
   | Field index for count_String not found on prototype thx.Arrays

---

Direct use with thx import (but different class)

using thx.Strings;
class Test {
	static function main() {
		trace(checkCount());
	}

	macro static function checkCount() {
		final arr = ['a', 'b', 'b', 'c', 'c', 'c', 'd', 'd', 'd', 'd'];
		final count = thx.Arrays.count(arr);
		return haxe.macro.Context.makeExpr(count, haxe.macro.Context.currentPos());
	}
}

fails with:

[ERROR] (unknown position)
   | Field index for count_String not found on prototype thx.Arrays

import + static extension

using thx.Arrays;
class Test {
	static function main() {
		trace(checkCount());
	}

	macro static function checkCount() {
		final arr = ['a', 'b', 'b', 'c', 'c', 'c', 'd', 'd', 'd', 'd'];
		final count = arr.count();
		return haxe.macro.Context.makeExpr(count, haxe.macro.Context.currentPos());
	}
}

fails with:

[ERROR] (unknown position)
   | Field index for count_String not found on prototype thx.Arrays

direct use without import

class Test {
	static function main() {
		trace(checkCount());
	}

	macro static function checkCount() {
		final arr = ['a', 'b', 'b', 'c', 'c', 'c', 'd', 'd', 'd', 'd'];
		final count = thx.Arrays.count(arr);
		return haxe.macro.Context.makeExpr(count, haxe.macro.Context.currentPos());
	}
}

success:

Test.hx:4:,[d => 4,c => 3,b => 2,a => 1]

Expected behavior

Method works direct and as static extension in macros, when importing any thx class
