#7078: Panic using mixing list with parallel arrays incorrectly
-------------------------+--------------------------------------------------
Reporter: NeilJ | Owner: chak
Type: bug | Status: new
Priority: normal | Milestone:
Component: Compiler | Version: 7.4.1
Keywords: | Os: Unknown/Multiple
Architecture: x86 | Failure: Compile-time crash
Difficulty: Unknown | Testcase:

-------------------------+--------------------------------------------------
Changes (by chak):
* failure: GHC rejects valid program => Compile-time crash
Comment:
GHC shouldn't panic, but instead give a proper error message, but the
definition of transpose in Handy.hs is incorrect. It uses list pattern
matching with `(:)` for parallel arrays. That is impossible as they are
not inductively defined.
