The isomorphism between the sources could be tweaked. For instance, around line 26 on the iGo side, there's a newline that doesn't appear on the other side, and the closing brace is right next to func main. On line 48 in iGo, note the comment ends up after the braces of something that should have already been closed out. In general, braces seem to end up with an extra line on the end too often.
I do not like the do syntax; for a very dubious improvement in syntax, you turn an N-parameter function into an N-1 parameter function visually. This is a net loss. (Go is not curried.) It's not even a huge character win, given that you've already disposed of the braces. I'm not convinced those stack very composably either, though I'll admit I'm not taking the time to prove that.
In fact, in general be wary of that issue in syntax, real code will encounter all the corner cases that can possibly exist as the elements are composed together. Can I call a
with your do syntax being used twice? If not, or if it's not easy, that's a bad sign. Vanilla Go I can type that correctly the first time... it may be a lot of braces but it's unambiguous. It may be wise to avoid trying to sugar function applications like that, if you can possibly avoid it.
