It is pretty much not like anything else around (although it has been already compared to "brainfuck") and the reason for its creation will be made apparent at a later time.
Rather than describe the whole thing in detail I'll just show a couple of examples:
@hello=`Hello`world!`
!hello
would result in the output:
Hello world!
a more sophisticated example is as follows:
@final=?=z_?!_~x_~y_~z
@reverse=?x!final_>x,y_@assign=@x=abcdefghijklmnopqrstuvwxyz_!reverse
@test=@x=?_@y=_@z=_?x!assign_!reverse
!test
which would result in the output:
zyxwvutsrqponmlkjihgfedcba
and if you then did this:
!test
you'd see this:
abcdefghijklmnopqrstuvwxyz
