Shrewd brainfuckers will have noticed that the aforegiven artistry has seemingly run afoul with recent perl incarnations. Versions 5.20+ exhibit severe indigestion upon encountering this following construct: 

$ perl5.20.2 -e '/(?{ ++vec($x,0,1) })/'
Segmentation fault

But worry not, my brethren, for the remedy is at hand. Leveraging the remarkable prowess of a technology known as Inline::C, we are proud to have solutioned the next generation, industrial-grade tooling that is bound to meet, if not exceed, the demands of the hardcore brainfucker elite. Here it is, for your perusal, for your enjoyment: 

#! /usr/bin/perl

use Inline C => Config => CC => 'clang';
use Digest::SHA q(sha1_hex);

open(CODE, '>', \my $code);

my $ind = 0;
sub o { print CODE "  " x $ind, @_, "\n" }
sub br { o 'while(*d) {'; ++$ind }
sub be { --$ind; o '}' }

sub pre { o << ''; ++$ind }
#include <stdio.h>
static void ich(unsigned char *d) { int c = getc(stdin); c < 0 || (*d 
+= c); }
static void och(unsigned char *d) { putc(*d, stdout); }
static unsigned char data[30000];
void run() {
  unsigned char *d = data;

undef $/;
<> =~ m{
  \A (?{pre})
  ((?: [>] (?{o '++d;'}) | [+] (?{o '++*d;'}) | [.] (?{o 'och(d);'}) |
       [<] (?{o '--d;'}) | [-] (?{o '--*d;'}) | [,] (?{o 'ich(d);'}) |
       [[] (?{br}) (?1) []] (?{be}) | [^][<>.,+-]
  )*+)
  \z (?{be}) }x  or die "Alzheimer";

Inline->bind(C => $code, NAME => '_'.sha1_hex($code));  run();
