[Seaside] how to render access to a JS argument variable?

I was looking at the JQuery API at
which says it can take a "htmlString or Element or Array or jQuery",
OR a Function. I mistakenly thought Seasides helper methods could
support all the types. They don't.

Yes, call:with: does. I was just suprised that Seaside's helper
method, JQueryInstance>>#replaceWith: can only support the htmlString
argument variation, not Element nor Array nor jQuery nor Function.
For those, one must write the #call:with: variation. Given all the
other ways Seaside lets me write terse code, I was fooled for an
entire afternoon into thinking I could shoe-horn it in via
replaceWith: helper method. :/

Hm, looking closely, it seems like replaceWith: does only ever produce
self call: 'someFunction' with: (self render: aRenderable)
and by call:with: implemented as:
self call: aString withArguments: (Array with: anObject)
then what we get for the withArguments: is always an Array of one
It seems like if the replaceWith: were implemented as:
self call 'replaceWith' with: aRenderable
then maybe they could support all the argument variations specified at
api.jquery.com, and not only the String variations.
And, indeed, the *vast majority* of senders of call:with: simply pass
the argument directly, thus truly providing merely the syntactic sugar
and nothing more.. But, for some reason, #after:, #append:, #before:,
#html:, #prepend:, #replaceWith:, #wrap:, #wrapAll:, #wrapInner: all
have that (self render: aRenderable) which forces the String arg...
