`+=` a different operator than `+`. `+` is symmetric while `+=` isn't.
I guess I should have been more explicit. I'm sorry for the confusion.
First, Tamgu is a language in which the recipient variable defines the context in which the instruction is evaluated.
If your recipient variable is an integer then everything on the right side of your assignment will be treated as an integer. If it is a string, well everything will be treated as a string.
We use this approach in many other instances:
int pos;
vector v;
string s="This is a testing case";
pos = "i" in s; //we are looking for "i" in the string
In this case, pos==2.
v = "i" in s; //we are looking for all positions of "i" in the string
v == [2,5,14]
string s="This is a testing case";
println("i" in s);
No offence but without some overriding principle, and a justification for that principle (that "things are demonstrably easier if you do it this way"), you've just dumped and extra load on the programmer which I do not need!.
Well, I did my fair share of programming over the years in so many different languages (Pascal, Cobol, C, C++, Java, Python, APL, Lisp, Prolog, Basic, Small Talk, various assemblers) that I honestly cannot remember all of them.
Tamgu is the result of this experience and my choice was always towards compactness and readability, with Perl being my personal nemesis.
The advantage of this approach is that you don't need to remember a long list of operators, they are simply re-interpreted in context and the re-interpretation is pretty consistent over most of the code.
But, well as the adage goes: Of tastes and colors...
println(vector("i" in s));
Having said that, if it works for you, awesome. Don't let me tell you otherwise, not everything has to be to my taste, after all.
