# Templates

    template byaddr(lhs, typ, ex)

  Allows a syntax for lvalue reference, exact analog to `auto& a = ex;` in C++

  Examples:

      var s = @[10, 11, 12]
      var a {...}{.byaddr.} = s[0]
      a += 100
      doAssert s == @[110, 11, 12]
      doAssert a is int
      var b {...}{.byaddr.}: int = s[0]
      doAssert a.addr == b.addr
