The grammar is underspecified. The full grammar is more complex. I guess I need just remove the current version from docs. Now it is confusing indeed. > Why is "c" not being replaced with "da"? It is all about precedence. According to the discussion I think I've chosen a wrong one and it raises confusion. Current version of precedence table is this: | 1 | Escaped characters | \<special character> |
| 2 | Bracket expression | [] |
| 3 | Grouping | () |
| 4 | Single-character-ERE duplication | * + ? {m,n} |
| 5 | Transduction | : |
| 6 | Concatenation | . (implicit) |
| 8 | Alternation | | | So the ':' is stronger then '.' (implicit concatenation). |
