One of my friends like to use the expression “balloon boy” to everything that gets a lot of attention but it turns to be a lot less interesting in the end.
Go is a new language created by Google that recently went open source and generated a lot of buzz in the interpipes.
As someone who have been working as programmer for almost 20 years and worked with almost a dozen languages and, on top of that, have a blog, I think I’m entitled to give my biased opinion about it.
One of the first things that got me off was the video pointing that the language is faster. Or the compiler is. Honestly, pointing that you become more productive because your compiler is fast is utterly wrong. If you’re aiming for a new language and you want people to be productive with it, make it so it’s easier to write code right in the first time. If you need to keep compiling your code over and over again till it does the right thing, you should probably check if there isn’t any impairment in the language itself that prevents right code to be written in the first place.
Which brings us to my second peeve about Go: The syntax, as presented in the tutorial. Syntax, in my opinion, is the biggest feature any programming language have to offer. If the syntax is straightfoward and easy to understand, it makes easier to have multiple developers working on the same code; if the language allows multiple “dialects” (or ways to write the same code), each developer may be inclined to use a different approach to write the code (which basically does the same thing) and you end up with a mess of a code where most developers would feel like rewriting than fixing a bug or adding a feature.
The first thing that caught my eye was the “import” statement that at some point uses a name before it and a block in the second example. Why two different ways (well, three if you count that one is probably optional — in the middle of the statement, nonetheless!) to import other packages with the same command?
Variable declaration also feels weird. “a variable p of type string” is longer to read than “a string p” (comparing
var p string := ""; with C way
string *p = "";). And that goes on. If you keep reading the statements in their long form (expanding them to natural English), all commands start to feel awkward and adding unnecessary cruft on the code, things that could be easily dismissed and force people to do less typing.
So far, those were my first impressions of the language and, as you can see, it was not a good first impression. Focusing on compile speed instead of code easiness/correctness seems out of place for current IT necessities and the language seems to pick some of the worst aspects of most languages around.
