defun a function that formats your src block, then use it in a header
:var x=(foo "src-block-name")
or maybe wrap (foo ...) in a `format' call or `prin1-to-string' call.
An example is below.

Another alternative is to use this idiom (see 14.10 Noweb reference syntax)
<<code-block-name(optional arguments)>>
where the code-block-name specifies a formatter (in elisp, say) and
the optional argument is the name of the code block you want to format.
