The objective here is easy: improve the debugging experience of the Perlang compiler by making all Stmt and Expr subclasses have a good (preferably, excellent) ToString() implementation. This method is typically called by debuggers when viewing the contents of local variables and parameters.
Here's what it looks like right now:
The screenshot above illustrates this well. Stmt.Var has a good implementation, where it virtually reconstructs the Perlang source code (var i = 12). Stmt.ExpressionStmt and Stmt.Print are much harder to debug; you more or less have to manually inspect these variables to get a glimpse of what's going on.
This should be pretty straightforward for most expression types, and we should clearly call other ToString() methods recursively in this.
