It is very powerful, has history, shows previous calculations, and it's pretty darn quick too.
Of course, there are plenty more calculators, powerful too. I only mention calc because it bothers me that the name of this new project collides with it, without really providing anything useful beyond having been written in a fashionable language.

The latter part of your comment sounds a bit discouraging. I think the developer didn't mean any harm an probably didn't know about this one.
PS: The dev had replied in the thread. All is well I guess.

The project name was originally calc.go, but as you can imagine that didn't work out too well with `go get`.
Two programs, same funcionality, same name. Haven't we learnt anything?
