Returns undef, 0 or 1. Undef if its the first time C<changed> is
called on that perl line. 0 if not the first time and the parameters
differ from the last call on that line. 1 if not the first time and
the parameters is the exact same as they where on the previous call on
that line of perl source code.

=head1 JUST FOR FUN

=head2 brainfu

B<Input:> one or two arguments

First argument: a string, source code of the brainfu
language. String containing the eight charachters + - < > [ ] . ,
Every other char is ignored silently.

Second argument: if the source code contains commas (,) the second
argument is the input characters in a string.

B<Output:> The resulting output from the program.

Example:

 print brainfu(<<"");  #prints "Hallo Verden!\n"
 ++++++++++[>+++++++>++++++++++>+++>+<<<<-]>++.>---.+++++++++++..+++.>++.<<++++++++++++++
 .>----------.+++++++++++++.--------------.+.+++++++++.>+.>.

See L<http://en.wikipedia.org/wiki/Brainfuck>

=head2 brainfu2perl

Just as L</brainfu> but instead it return the perl code to which the
brainfu code is translated. Just C<< eval() >> this perl code to run.

Example:

 print brainfu2perl('>++++++++[<++++++++>-]<++++++++.>++++++[<++++++>-]<---.');

Prints this string:

 my($c,$o,@b)=(0); sub out{$o.=chr($b[$c]) for 1..$_[0]||1}
 ++$c;++$b[$c];++$b[$c];++$b[$c];++$b[$c];++$b[$c];++$b[$c];++$b[$c];++$b[$c];
 while($b[$c]){--$c;++$b[$c];++$b[$c];++$b[$c];++$b[$c];++$b[$c];++$b[$c];++$b[$c];
 ++$b[$c];++$c;--$b[$c];}--$c;++$b[$c];++$b[$c];++$b[$c];++$b[$c];++$b[$c];++$b[$c];
 ++$b[$c];++$b[$c];out;++$c;++$b[$c];++$b[$c];++$b[$c];++$b[$c];++$b[$c];++$b[$c];
 while($b[$c]){--$c;++$b[$c];++$b[$c];++$b[$c];++$b[$c];++$b[$c];++$b[$c];++$c;--$b[$c];}
 --$c;--$b[$c];--$b[$c];--$b[$c];out;$o;

=head2 brainfu2perl_optimized

Just as L</brainfu2perl> but optimizes the perl code. The same
example as above with brainfu2perl_optimized returns this equivalent
but shorter perl code:

 $b[++$c]+=8;while($b[$c]){$b[--$c]+=8;--$b[++$c]}$b[--$c]+=8;out;$b[++$c]+=6;
 while($b[$c]){$b[--$c]+=6;--$b[++$c]}$b[--$c]-=3;out;$o;

Update Acme::Tools to newest version quick and dirty:
