Bug description

I've just seen that I can write :

if 0b0=0b0then 1 else 0

without any space between "0b0" and "then" !

Could that be in purpose ?! I hope not. :-)

How can I delete a report ?! ...

I've seen that it can be done with any numbers... (any handled base)

So it must be on purpose...

Still I believe it's not really "clean" ...

Nothing to do with binary literals specifically, e.g.
if 0=0then 1else 0 is OK as well. This is a consequence of the "longest match" convention for the lexer, and there is really no reason to change it.
