I think maybe you just didn't understand the idea.

I propose to simplify everything by throwing out some seed 
abstractions and classes. Because that they are not needed by 99% 
of users, and those who will need them easily will make them 
themselves (I will show how below)

And also I suggested simple functions (not classes with ctros and 
methods) for just. obtaining. randomized. buffer. (that are 
currently lacking because we are afraid to break the laws and get 
caught by the crypto-police)

(I thought that maybe proposed functions will be compatible with 
betterC? Hmm)

I ignored it because I thought the answer was obvious. No one 
will take away your seeding and `Random()`:

"seed" is just "true random" sequence, yes? It will be provided 
by `std.random.truerandom.getTrueRandom()` call
`Random()` is just one of `std.random.predetermined` functions

That's all. And you know what it is and how it works.
