Some syntax review

[Аркадий Рост]

Well, in general Go language looks pretty good, but I'm a bit
disappointed with function declarations. In fact, I think functions
syntaxes is not as good as it ought to be.

I expected something like this:

func say (who string, what string) -> (string)
{
return who+what;
}

or

func greet (what string) -> ()
{
ftm.Println(what);
}

I think that this syntaxe for function declarations is much simple and
easy to use.

Why type extra characters when you can avoid them? :-)

Well, it's not very difficult, but makes code more obvious so I think
it worse it. If some one don't want type exra characters they may be
implemented as syntax sygar.

A lot of syntactic sugar is unnecessary if readability is not a goal ;). Separating parameters and return values with some sugar makes signatures a easier to read (for me, at least).

Take care,

Agree, but I think ")" is okay as a separator :)

Also, Go already has <- operator that has a different meaning than the
proposed ->.

Here you go:

func say (who string, what string) /* -> */  string

I don't thinkthat ")" is a really good separator(for example, for
multiple return values).For me it will be better to use ->.

If you want to highlight return types, tell your editor to color them
differently. I find that Go is much easier to read with syntax
highlighting on.
