132 | =head1 CAVEATS | ||||
133 | |||||
134 | Compared to Perl, the number tokenizer is too liberal about allowing | ||||
135 | underscores anywhere. For example, the following is a syntax error in | ||||
136 | Perl, but is allowed in PPI: | ||||
137 | |||||
138 | 0_b10 | ||||
139 | |||||
140 | =head1 TO DO | ||||
141 | |||||
142 | - Treat v-strings as binary strings or barewords, not as "base-256" | ||||
143 | numbers | ||||
144 | |||||
145 | - Break out decimal integers into their own subclass? | ||||
146 | |||||
147 | - Implement literal() | ||||
