'\n' is illegal in variable name and function name.'var a\nb=1' will throw a SyntaxError.So print 'TypeError: a\n is not a function.' may be not a good idea.It regard 'a\n' as a variable name.

But '\n' is meaningless in the end of variable name and function name and will be ignored.

If running the following program:
var a
=1;
print(a);
print(a
);
a=2;
print(a);
print(a
);

It output:
1
1
2
2

So during compilation,'\n' in the end of variable name and function name will be ignored.The '\n' of variable name 'a\n' will be ignored and 'a\n' is regarded as 'a'.

I think 'TypeError:a is not a function' is better.
