I need to parse an input set of characters with the following results :

You can do this by intersecting with 'm'.
action a { if ( !foo ) error(); }
m = (any @a)*;
This logic would be used for every character in the string. The intent is to
show exactly where the failure has occurred on the input string versus the
expected string.
Ideally the error call could have a parameter such as an offset to indicate
where within the string the match failed.
Any ideas would be greatly appreciated.
Also, you may want to use an error action.
