Is it reviewable? Sure.
Should we review? I guess, if someone feels so inclined--but why?
But for me, there's not much point to it. It's truly a toy-language. No one will ever write any serious production code out of it. Moreover, the example questions we have of it show that the language itself encourage ridiculously named variables.
Consider, the following snippet in C:
char * CHEEZ = "CHEEZ";
char * BURGR = "BURGR";
char * WAFLZ = "WAFLZ";
char * SEEKRITMOOV = "ZPOCK"
What's the first thing you comment on if you see something like that on Code review? For me, it's something like:
This is your source code, not an Internet forum. As such, I highly recommend you put a bit more effort into your variable names.
Even if all caps is the naming convention for variables, these sorts of variable names seem to be encouraged by the lolcode language... as such, virtually every lolcode post is going to have them. Meanwhile, you use the same silly names in literally any other language on the site, and that's going to be commented on in at least one of the answers to the question. It's going to get tiresome making this same comment on literally every lolcode question that gets posted.
Moreover, sometimes when someone posts a question in which they're interacting with a database, sometimes the answer to a question about their C# source code might be to improve the query, or sometimes the answer to a question about their query might be to improve their C# code (just as an example). Given how silly and hard to follow lolcode is, wouldn't the appropriate answer to any lolcode question be to instead write the source code in a language that can actually be read and made sense of by a human?
Whether we allow or don't allow them, either way I'm fine. After all, I don't have to review them, but I think I may pretty much categorically be downvoting all lolcode questions (and probably brainfuck as well).
