Hi, I take a look at the code. It does support [0-9] also.
[yohgaki@dev tests]$ php -r "\$a = ' a10';for (\$i=0; \$i<10;\$i++) var_dump(++\$a);" string(4) " a11" string(4) " a12" string(4) " a13" string(4) " a14" string(4) " a15" string(4) " a16" string(4) " a17" string(4) " a18" string(4) " a19" string(4) " a20" It sounds good to have string decrements. 2013/7/19 Peter Lind <peter.e.l...@gmail.com> > Interesting to note that although Perl 6 is apparently capable of > decrementing strings, it doesn't fully mirror the incrementing: > > http://feather.perl6.nl/syn/S03.html#line_516 > > Specifically: decrementing 'AAA' would not turn into 'ZZ' but would error, > according to that link > Carry handle of decrements is more complex than increments. It may be the reason. Regards, -- Yasuo Ohgaki yohg...@ohgaki.net
