You use 01 02 03 04 .. 07 as array indices, which is unusual. I suspect these number get interpreted as octal numbers instead of decimal numbers, hence 08 would be to big for the base and it should be 10 (equals decimal 8).

ppi::token::number5.18
PPI::Token::Number(3) User Contributed Perl Documentation PPI::Token::Number(3)
NAME
PPI::Token::Number - Token class for a number
SYNOPSIS
$n = 1234; # decimal integer
$n = 0b1110011; # binary integer
$n = 01234; # octal integer
$n = 0x1234; # hexadecimal integer
$n = 12.34e-56; # exponential notation ( currently not working )
INHERITANCE
PPI::Token::Number
isa PPI::Token
isa PPI::Element
DESCRIPTION
The "PPI::Token::Number" class is used for tokens that represent numbers, in the various types that Perl supports.
METHODS
base
The "base" method is provided by all of the ::Number subclasses. This is 10 for decimal, 16 for hexadecimal, 2 for binary, etc.
literal
Return the numeric value of this token.
CAVEATS
Compared to Perl, the number tokenizer is too liberal about allowing underscores anywhere. For example, the following is a syntax error in
Perl, but is allowed in PPI:
0_b10
TO DO
- Treat v-strings as binary strings or barewords, not as "base-256"
numbers
- Break out decimal integers into their own subclass?
- Implement literal()
SUPPORT
See the support section in the main module.
