Declare a variable with type

[gogotanaka]

int i = 1
String str = "abc"

How do we freeze variable itself or check type at every reassigning?

The declaration should be trivial, we probably don't even need local_variable for that, just make def int check it's argument. As for tracking the variable, at first look it seems impossible.. Without doing source inspection, I can't even think of a way to infer the name of the instance variable from def int

But checking at declare time is probably good enough.

Can you do String str; in Java? I know you can do public String str; in a class to declare members without assigning a value, so you can probably do that in local scope too?

@chancancode Thank for adding me to the repo! I'm honored.

I agree with you. It may be impossible or need dirty hack.
Anyway I start to implement defining method with checking it's argument. After that, I think about declare a variable.

oh, you'er totally right. sorry it's my mistake ; (

Sorry if it wasn't clear (I was typing on my phone), the last point was more of a question. I just checked and answered my own question, you can indeed do all of these in Java:

String a = "abc";
String b;
int c = 1;
int d;

I suppose String b and int d would just be no-ops in the gem, but it would be quite tricky to get that work unless you method_missing everything and return :variable_declaration or something like that...
