Learned monks ... I am working on some very long Ints using the textural representation of a number and summing the digits. For example SumDigits(312023) = 3+1+2+0+2+3 = 11. Sometimes there is a need to split very long strings and interpret those as numbers separately. A small example 312023 => 321 and 023. Perl is generally quite forgiving about moving between strings and integers but unfortunately this stumbles on a feature from the dark ages of computing. Consider 
perl -e 'print 312023," ",312," ",23,"\n";'

312023 312 23

and 
perl -e 'print 312023," ",312," ",023,"\n";'

312023 312 19

In the second example the third part "023" is interpreted as octal ( base 7 ) and becomes 2*8+3 decimal 19. I am neutral about 0x23 interpreted as hexadecimal but can this ancient octal feature of perl be switched off ?
