tracker issue : CF-4198801

Problem Description: When fully quoting variable name assignment using dynamic keys, coldfusion errors when attempting to use a key that STARTS with a number. eg, "12345User" throws, but "User12345" does not.

Steps to Reproduce: The following code demonstrates the issue:

variables.key1 = "abc";
"variables.#variables.key1#" = "key1 works";

variables.key2 = "123";
variables[ variables.key2 ] = "key2 works!";

variables.key3 = "abc123";
"variables.#variables.key3#" = "key3 works!";

variables.key4 = "123";
"variables.#variables.key4#" = "key4 works!";

variables.key5 = "123abc";
"variables.#variables.key5#" = "key5 works!";

writeDump( var=variables );

Actual Result:

"Error: The string VARIABLES.variables.123 is not a valid ColdFusion variable name"

Expected Result:

All 5 keys should work using this notation.

Any Workarounds:

Use square bracket notation. However, this is not necessarily practical, as some javascript libraries that we use are sending the data in the format 'data[123][abc] = "this is some data"', where most other languages will automatically translate this to a struct, I have been using the quoted string notation as above to translate to struct data. Given that the depth of structs/keys could vary, it's far simpler to have it assigned this way, without needing to manually parse the keys and build up the resulting data struct in cf.
