Handle tagged templates more fluently

Here’s an example with the parse:

taggedTemplate`hello ${firstName}`;

> program
>> expression_statement
>>> call_expression
>>>> arguments: template_string
>>>>> template_substitution
>>>>>> identifier
>>>>>> "firstName"

I wonder if the template_string could be referred to as a string, the function identifier as name and then each template_substitution as an argument.

Edit @pokey

We will do the following to handle this issue:

• #90
• #645
• #646

Argument sounds good to me

This sounds great to me, thanks!
