surprisingly enough for me, the exact same point was raised by others too. meanwhile, i was totally unaware that many would find it hard to read it as i never ever had any difficulty telling them apart even with the (admittedly baroque) design of the braces. if that is the only feature stopping you from trying this, please make a feature request. maybe i could issue a "disambiguous braces" variant.
I'm gonna raise another point, however. I think Myna's braces are easier to distinguish from each other: "(" and "{". After spending all day coding, they start to look very similar. I agree it might not be super beautiful, but for me, Myna has this advantage.
