# Mola Errata List
: Using these lists saves significant rehearsal time by allowing librarians to correct errors in advance rather than identifying them during expensive ensemble time.
It was... wrong.
When the top layer is pulled too tight by the presser foot, the fabric “tunnels”—creating a raised ridge of un-stitched material between parallel cuts. Collectors look for flat panels. If a mola has tunneling longer than 1 inch, it appears on the Errata List as a visual obstruction.
| Errata ID | Title | Version / Section | Type | Reported Date | Impact | Proposed Correction | Status | |---|---:|---|---|---:|---|---|---| | MOLA-ERR-001 | Incorrect example for array indexing | 1.2 / 4.3.1 | Bug | 2026-03-15 | High — causes runtime misinterpretation | Change example index from 1..n to 0..n-1 and add note about zero-based indexing. | Implemented | | MOLA-ERR-002 | Ambiguous definition of "merge" operation | 1.2 / 7.1 | Ambiguity | 2026-03-20 | Medium — different implementations behave differently | Clarify merge semantics: define precedence, conflict resolution rules, and order of application. | Proposed | | MOLA-ERR-003 | Typo: "commas" -> "colons" in grammar | 1.1 / Appendix A | Typo | 2026-02-02 | Low — documentation only | Replace "commas" with "colons" in grammar production G-12. | Accepted | Mola Errata List
Reality: There is no scientific evidence to support the claim that Mola species are poisonous. While some species of sunfish may have a mildly toxic flesh, Mola species are considered safe for consumption.
Membership in MOLA is invaluable for professional development, providing access to this specialized knowledge. How to Access and Use MOLA Errata The MOLA Errata Database is proprietary to its members. # Mola Errata List : Using these lists
The alternative is discovering errors during a paid rehearsal. the source notes. By preparing parts in advance, librarians ensure that the first rehearsal is productive and focused on music-making, not troubleshooting.
The MOLA Errata database is a . It is designed specifically to help MOLA members improve efficiency in their libraries. When the top layer is pulled too tight
Even the most widely performed historical works are riddled with modern print errors.
Without the MOLA database, a librarian would have to manually compare every single printed page against the conductor's full master score—a process taking dozens of hours per piece.
