* merge magics * merge metatype tests * merge method tests * merge objects tests * change `import future` to `import sugar` Nim in Action tests are left with `import future`, to ensure compatibility. * merge overload tests * merge proc tests * merge procvar tests * merge range tests * merge seq tests * merge sets tests * remove wrong assert from `tsets3` * fix `jsTests` * better fix
