Acme::Anguish - Use Anguish programming language in your Perl 6 programs
anguish "\x2061" x 72 ~ "\x2063"; # prints "H"
Anguish is a Brainfuck variant
that uses invisible Unicode characters instead of traditional Brainfuck's ones.
Here's the mapping of Brainfuck operators to Anguish:
>  U+2060 WORD JOINER [Cf]
<  U+200B ZERO WIDTH SPACE [Cf]
+  U+2061 FUNCTION APPLICATION [Cf]
-  U+2062 INVISIBLE TIMES [Cf]
.  U+2063 INVISIBLE SEPARATOR [Cf]
,  U+FEFF ZERO WIDTH NO-BREAK SPACE [Cf]
[  U+200C ZERO WIDTH NON-JOINER [Cf]
]  U+200D ZERO WIDTH JOINER [Cf]
All other characters are silently ignored.
The meaning of original Brainfuck characters are as follows:
> increment the data pointer (to point to the next cell to the right).
< decrement the data pointer (to point to the next cell to the left).
+ increment (increase by one) the byte at the data pointer.
- decrement (decrease by one) the byte at the data pointer.
. output the byte at the data pointer.
, accept one byte of input, storing its value in the byte at the data pointer.
[ if the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command.
] if the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command.
Takes a single positional argument: string of Anguish code to evaluate.

BUGS AND CAVEATS
U-FEFF character also serves as a file
BOM, so avoid using it
as the first character in your file.
