NamedControl: a better way to write SynthDef arguments

I suppose an interesting application is to exploit the fact that the names are strings when passed to NamedControls do a sort of meta-programming to generate multiple controls from the same function “pattern” as discussed here. In a nutshell example:

(
f = { Poll.kr(Impulse.kr(1), ~ctrl.asSymbol.kr, ~ctrl) };

SynthDef("funny_ctrls", {
	SynthDef.wrap({ (ctrl: "boo").use { f.value } });
	SynthDef.wrap({ (ctrl: "yoo").use { f.value } })
}).add;

x = Synth("funny_ctrls");

s.queryAllNodes(true)
)
