No tests for variables

[b1ek]

I just noticed that none of the validity tests check if variables are behaving correctly.

some ideas for tests:

1. redefinition of variables

   let var = "abc"
   let var = 123
   

2. global ids, especially that when variable is accessed it uses the same id as it was when it was assigned
3. a ton of other stuff, like accessing a variable from another scope and whatnot

I think that we need a list of every kind of statement and expression and check od we have tests for it

In validity there are a lot of tests but I don't think that there is one like this.

@KrosFire Do you mean some kind of features.txt so that we can keep it as a checklist for all of the features that Amber currently has?

@Ph0enixKM I'm thinking of code coverage. Some anayltics tool to show us what we're missing in tests
