Let say there are 5 non-terminal symbols: nt_1 nt_2 nt_3 nt_4 nt_5
In nt_5, I want to use every other non-terminal except nt_2.
For this I have to write like:
nt_5: /* empty */ { ... }
| nt_5 nt_1 { ... }
| nt_5 nt_3 { ... }
| nt_5 nt_4 { ... }
;
Now my question is that, is there any way by which I can negate nt_2 while
creating nt_5 ?
