Lexer -> ID Rules

Hello,

are there any hard reasons why account names must not start with numerical values? Tackler uses the following definitions:

ID: NameStartChar (NameChar)*;

The above ANTLR fragment 'NameStartChar' excludes numbers.

In my usecase the account names uses numbers and I have no control or way to avoid that - they look like '4zifortyz64av'. A kind of mapping (x -> account) would be of course possible but would add additional complexity.

I also have to admit that I tested my accounting schema with 'hledger' until now and I'm about automating the process on the JVM and therefore Tackler is of course the first choice.

Thank you.

Regards, Jiri
