I'm one day in on learning Go lang and I can already sense that my least favourite language feature is the use of backticks " ` " for string literals.
One reason: backtick is a dead key on my language layout. I have to press shift+`+` to get one.
Another reason: If I miss hitting it twice, then press a letter, I get something like Èrror` when I meant `Error`. Easy to miss.
Third reason: with my crappy eyes, the difference between ` and ' is barely visible.
