Acme::Anguish - Use Anguish programming language in your Perl 6 programs
use Acme::Anguish; 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.
