No, it's an s-expression... it may be a function call, but it may also be a macro, and inside a macro it may be a parameter list or a number of other things.
In my experience, people simply go "Doh, of course!" or don't write the wrong code in the first place. It has never caused me any real problems.
For those of you that may be curious, or not know C++, in C++ this:
Obj x();
is a declaration of a function called x that returns an Obj. Whereas this:
Obj x;
defines (possibly, depending on context) an instance of the type Obj called x.
Most people get over this pretty quickly.
If that is your main complaint about a language then the language doesn't have too many problems. Not that I'm suggesting that C++ doesn't have more serious problems.
I am an exception then. Rust may be my favourite language but the syntax is pretty awful and one of its biggest weaknesses. I also love Ruby but I am pretty meh about its syntax.
I don't think many people would start to use a language unless the found the syntax at least a little simpatico - but I guess they could be drawn by the semantics it provides.
