How to access a JSON structure key that starts with a number

Question

I've got an odd issue here.  I'm accessing someone else's JSON structure so I am not able to change it.  The JSON structure keys are named with both characters and numbers like this:
0
198456
product_id
198456
1

So, in other words, there's a key named "0" and a key named "product_id", both of which contain the same key.  Why they did that, I don't know, but they did.
In one of the instances, the data stored under the text-named key isn't the same as the numerical-named key.  I tried to output the data in the numerical key like this (it's an array of structures):
#strStompyJSON.data[1].0#
but I get the following error:
Invalid CFML construct found on line 41 at column 31.
ColdFusion was looking at the following text:
.0
When I do the following, it works fine:
#strStompyJSON.data[1].product_id#
So it looks as though CF doesn't like accessing a variable that starts with a number.  I am able to loop through the structure using a collection loop, and it outputs all of the keys (including the numerical ones) and their values using the following code:
<cfloop collection="#strStompyJSON.data[1]#" item="key">
#key#: #strStompyJSON.data[1][key]#<br />
</cfloop>
However, that doesn't allow me a way to access specific keys named with a number.  Is there a way that I can specifically access a key that is named with a number?
thanks!

No problem--glad it worked out.
As a follow-up to this, I'd encourage you to keep the bracket notation in mind during future development.  It is EXTREMELY useful in a lot of situations.
For example, if you're building a structure on the fly with dynamic keys, bracket notation is extremely helpful:
     <cfset authors = structnew()>
     <cfloop list="authorlist" index="name">
          <cfset authors[name] = getbooklist(name)>
     </cfloop>
Also, bracket notation is really nice when creating json from ColdFusion structures.  Consider this:
     <cfset author = structnew()>
     <cfset author.name = "Neil Gaiman">
     <cfset author.genre = "Fantasy">
     <cfset author.awesome = true>
     <cfset authorjson = serializejson(author)>
By default, the serialized json produced will have all UPPER CASE keys.  Not a big deal in most cases, but if you're returning the json to something (like a JS library) that is expecting keys in a certain case, it can be a problem.  Fortunately, bracket notation allows you to specify exactly what case you want the structure's keys to be in:
     <cfset author = structnew()>
     <cfset author['name'] = "Neil Gaiman">
     <cfset author['Genre'] = "Fantasy">
     <cfset author['AWESOME'] = true>
     <cfset authorjson = serializejson(author)>
