Problem:
Add a "var" attribute to <cfparam>
Currently <cfparam> is covering the following case (ignoring the type check):
<cfparam name="variable" default="defaultValue">
<cfset variable = isDefined("variable") ? variable : defaultValue>
Being able to specify a "var" attribute would also allow to cover the case in which to set another variable:
<cfparam name="variable" default="defaultValue" var="anotherVariable">
<!--- The above would be the same as this --->
<cfset anotherVariable = isDefined("variable") ? variable : defaultValue>
The use case here is, you want to check for the existance of a variable, but not want to overwrite it with the default value, if it's not existing. An example would be to check for an XML attribute:
<cfparam name="XMLContent.some.elements.down.XMLAttributes.id" default="0" var="id">
This would either save the id from the XML or 0 into the variable "id", but the XML won't be changed.
