I am glad of it, actually: it is better to work within a
well-structured model than constructing code out of strings.
But I personally dislike reflection, too, and hope that most
practical programs can be written in JavaScript without
either reflection or eval. As you see, I have employed eval
as a tiny convenience facility to imitate input/output
parameters, but of course it is not necessary as JavaScript
has other means of returning several scalar outputs from a
function, including object orientation (this),
desturcturing, and (for errors) exceptions.
