Returning a list with name/value pair parameters

Is it possible to return a List / TemplateSequenceModel from code that 
accepts parameters formatted as name / value pairs?

Here's what I want to do:

<#assign myList = myMethod(param0="value" param1="value")>

or

<#assign myList = <@myMethod param0="value" param1="value"/> >

The trouble with the first example is that the TemplateMethodModel above 
only accepts positional parameters, not name/value pairs.

The trouble with the second example is that I don't think this syntax works.

The reason I want name/value pairs is that the parameters are definitely 
going to change over time, and it's a lot easier to be backwardly 
compatible when you use them. You can add new ones and ignore old ones 
without a problem. With positional parameters, you're stuck.
