func.apply() gives identical functionality, but no syntax to make it
succinct. Like consider (assuming the syntax is **kwargs, like in Python)
<#assign commonParams = { 'style': 'foo', 'align': 'left' }>
...
<@my.fancyInput type='text' size=10 **commonParams />
With function.apply-style it's something like:
<@my?fancyInput?apply({ 'type': 'text', 'size': 10 } + commonParams) />
So that does the same without new syntax (it only adds a new built-in,
"apply"), but is more verbose, and it changes the look-and-feel of the
call a lot, just because you happen to need some dynamically added
parameters there.
