How to use the babel-core.types.memberExpression function in babel-core

function main(opts) {
  var t = require('babel-core').types;

  // main function declaration
  var expr = t.functionDeclaration(t.identifier(opts.main), [t.identifier(ELEM)], t.blockStatement([t.returnStatement(t.callExpression(t.memberExpression(t.memberExpression(t.identifier(opts.templates), t.callExpression(t.memberExpression(t.memberExpression(t.identifier(ELEM), t.identifier(TAG_NAME)), t.identifier(TO_LOWER_CASE)), []), true), t.identifier('call')), [t.identifier(ELEM), t.identifier(ELEM)]))]));

  return t.program([expr]);
}

  var t = require('babel-core').types;

  opts = opts || {};
