adding variable to context
seting variable values by multiple assignment
parsing, parsing, parsing!
I should begin with small things. For example... designing some input files, which
then tokenized should be parsed. Really simple stuff. And then I should check AST.
What actually has been build? Maybe for this kind of stuff visitor patter would be appropriate.
Visitor as a tester... hm... it goes around and remembers data. Different kinds of visitors. Not so bad
idea, actually. But that imposes some change in design. Actually not so bad changes.
So - designing input file
parsing input, creating AST
visiting AST, and getting data from it, comparing acquired data to data, we want to get
Smaller parts like creating AST Nodes. I don't know, for example some parts of parser. Maybe those parts
should become standalone functions, to be tested more easily?
My lexer doesn't have enough tests, i think. More tests! For example, given, acquired, desired.
And em, It'd be nice if I could run test from console like ./Sencha-lang --run-tests or something. Done.
