Proposed AST

Example 1 - Function body

function a(){
  uint x = 5
}

{
 "type": "FunctionDeclaration",
 "name": "a",
 "params": null,
 "modifiers": null,
 "body": {
  "type": "BlockStatement",
  "body": [
   {
    "type": "ExpressionStatement",
    "expression": {
     "type": "DeclarativeExpression",
     "name": "x",
     "literal": {
      "type": "Type",
      "literal": "uint",
      "members": [],
      "array_parts": [],
      "start": 8306,
      "end": 8310
     },
     "storage_location": null,
     "start": 8306,
     "end": 8312
    },
    "start": 8306,
    "end": 8313
   }
  ],
  "start": 8300,
  "end": 8317
 },
 "is_abstract": false,
 "start": 8288,
 "end": 8317
}

Example 2: Function body, extra spaces

function spaces()   {
    uint y;
}

{
 "type": "FunctionDeclaration",
 "name": "spaces",
 "params": null,
 "modifiers": null,
 "body": {
  "type": "BlockStatement",
  "body": [
   {
    "type": "ExpressionStatement",
    "expression": {
     "type": "DeclarativeExpression",
     "name": "y",
     "literal": {
      "type": "Type",
      "literal": "uint",
      "members": [],
      "array_parts": [],
      "start": 8346,
      "end": 8350
     },
     "storage_location": null,
     "start": 8346,
     "end": 8352
    },
    "start": 8346,
    "end": 8353
   }
  ],
  "start": 8340,
  "end": 8357
 },
 "is_abstract": false,
 "start": 8320,
 "end": 8357
}

Example 3: Abstract

function abstract();

{
 "type": "FunctionDeclaration",
 "name": "abstract",
 "params": null,
 "modifiers": null,
 "body": null,
 "is_abstract": true,
 "start": 8360,
 "end": 8380
}
