The simple answer on your question is:
eval('...');
The evaluation of MemberExpression return Reference which in abstract
view looks:
var reference = {
base : GlobalEnvironmentRecord,
referencedName : 'eval',
strictReference : false
};
While in:
this.eval('...');
var reference = {
base : GlobalObject,
referencedName : 'eval',
strictReference : false
};
So per first rule for direct call of `eval' defined in:
15.1.2.1.1 Direct Call to Eval:
The Reference that is the result of evaluating the MemberExpression in
the CallExpression has an environment
record as its base value and its reference name is "eval".
You should read "10 Executable Code and Execution Contexts" and you will
find the answer.
