The frontend calls tokenStartOfNode, getTextOfNode, getSourceFileOfNode and
forEachChild instead of AstNode's position and traversal methods. Node lists
answer hasTrailingComma(), and a declaration's modifiers are a modifier list
with their flags.
Symbol, Type, Signature, IndexInfo, TypePredicate, Program, TypeChecker and
Diagnostic have tsc-ts/api's members and types. Compiler code reads symbol
names with symbolName(symbol).
tsc-ts goes to 0.0.5. api-conformance.ts asserts that AstNode, AstNodeList,
SourceFile and each node interface are assignable to tsc-ts/api's interface of
the same name, and names the members where the wire format differs.
