Example code from the web:

// enclose (c)urly(b)races, (s)quare(b)brackets, (q)uotes:
'ecb is {"{",x,"}"}; 'esb is {"[",x,"]"}; 'eq is {"\"",x,"\""}; 
'jc is {join ","}; 'jac is {each y jc};  // join x with commas; apply y to each of x then join with commas
'pair is {encode,":",(y encode)};        // key:val pair for dict
'dict is {key as 'k; x val as 'v; [k],v >: pair jc ecb}; // get keys/vals, pair merge, commas, braces
// wrap non-scalar values in appropriate way:
'many is {as 'el type case ('char, {el str eq}, 'dict, {el dict}, {el jac encode esb})};
'encode is {ravel[many,str]};            // ravel calls x y[0] for arrays (len > 1), x y[1] for scalars
