Hello,

I have a rule like this:

version1 ---  rule1: (rule2 (a+ b* | b* a+) )* (rule2 a*)*

sometimes i would generate the code and in the code for the func
corresponding to rule1:
i would have a call like: cdfa9.predict(...)

then let's say i modify the rule to

version2.1 ---- rule1: (rule2 (a+ b* | b* a+) )*  *|* (rule2 a*)*
or to
version2.2 ---- rule1: ( (rule2 (a+ b* | b* a+) )*  ** (rule2 a*)*)*

then generate

then remove the change (i.e. return to rule version1 above)
then generate,

i'd would find sometimes that the call for cdfa9.predict(...) disappears.

Thank you for your time :)
