Int ambigious

[h4ck3rm1k3]

Hi there,
thanks for this great project.

I found an interesting case where the json generated is not parsable.

Input https://github.com/h4ck3rm1k3/gogccintro/blob/master/parser/ast/Ast.go

generates :
https://github.com/h4ck3rm1k3/gogccintro/blob/master/parser/ast/Ast_ffjson.go

But I needed to hack the generated code
https://github.com/h4ck3rm1k3/gogccintro/blob/master/parser/Ast_ffjson.go

for example :
https://github.com/h4ck3rm1k3/gogccintro/blob/master/parser/Ast_ffjson.go#L979
where I allow for a string representation of the int.

mdupont@debian-build-speed:~/experiments/gogccintro/parser$ head -12 gccpretty.json 
{
  "Count": {
    "TheCount": 2311442
  },
  "NodeTypes": {
    "\n": {
      "Count": {
        "TheCount": 399
      },
      "AttributeCount": {
        "2": { 

The problem is in the 2 on the last line for example.
