Syntactic Sugar for Patch chugin (aka simple & easy LFOs) about chuck HOT 2 OPEN

yeah I guess one fully shaven yak version of this is 
support for variable rate processing graphs (e.g. SinOsc lfo.rate(10::hz) => (scaling, etc) => ug.param;
support for arbitrary math in ugen chains (SinOsc s / 2 => dac;) or something
IMO its super useful to just have arbitrary math/expressions/functions instead of a bunch of one-off ugens for scaling/etc. because then you can easily do like dB, exponential, and various other transforms easily
also unlocks fun stuff like exponential FM

IMO arbitrary expressions + multi-rate => params is a game changer
probably 75% of the chuck Ive ever written I could just delete haha 

imagine having an envelope follower ugen and just hooking it up like
 adc => EnvFollower e => sin.gain; 

SinOsc mod => SinOsc car => dac;
2 => car.op;
Gain g.rate(10::hz) * hid.mouseX * 100 => mod.freq;
Gain g.rate(10::hz) * hid.mouseY * 100 => mod.gain;

why not just let there be constants?
0.5.rate(10::hz) => osc.gain;
