tracker issue : CF-3594992

Problem Description:
As per title - in certain situations lines of code do not execute - the parser appears to get confused by inline structs inside function calls - but only if using named arguments and inside a block (if/for/try/etc).

This is very similar issue to https://bugbase.adobe.com/index.cfm?event=bug&id=3482734 - however, whilst that issue was "fixed" in CF10 update 11, the code below still errors on 10,0,11,285437

Steps to reproduce:

	<cftry>
		<li>Example 1 - named argument, inline struct referencing variable, inside if block.
	<cfscript>

			if ( true )
			{
				IgnoredVar = 1;
				writeOutput(StructKeyExists(Variables,'IgnoredVar') );

				doStuff
					( Type = 'json'
					, Data = { success:false , error:IgnoredVar }
					);

				writeOutput(StructKeyExists(Variables,'IgnoredVar') );
				StructDelete(Variables,'IgnoredVar');
			}

	</cfscript>
	<cfcatch>
		<cfoutput><b style="color:red">Failed</b>: #cfcatch.message#</cfoutput>
	</cfcatch>
	</cftry>

	<cffunction name="doStuff" output=1 >
		<cfargument name="type" />
		<cfargument name="data" default=#{undefined:1}# />
		<b style="color:green">function called</b> #StructKeyList(Arguments)# #StructKeyList(Arguments.Data)#
	</cffunction>

See attached code for further examples...

Expected result:
No error.

Any Workarounds:
1. Create struct as variable before function call.
2. Use Railo, which doesn't have any issues.
