2OP: sorry, i can barely read that code. this has nothing to do 
with your skills, it is the topic -- i've never seen clean lazy 
evaluation code. after all, this is a hack.

still, i think that such a library worth at least some work.

as for "is my code/approach is good enough", i know only two 
answers.
1. yes, 'cause it works.
2. no, 'cause it doesn't work.
so if your code works, it is good. ;-)

i mean that such hacks will be somewhat ugly anyway, so just 
write a brief explanation in comments and go on.

sorry, it is probably not what you wanted to hear... ;-)
