|
After GHC 7.4 a new `casMutVar#` primop became available, but it's
|
|
difficult to use safely, because pointer equality is a highly
|
|
unstable property in Haskell. This library provides a safer method
|
|
based on the concept of "Tickets".
|
|
|
|
Also, this library uses the "foreign primop" capability of GHC to
|
|
add access to other variants that may be of
|
|
interest, specifically, compare and swap inside an array.
|
|
|
|
Note that as of GHC 7.8, the relevant primops have been included in GHC itself.
|
|
This library is engineered to work pre- and post-GHC-7.8, while exposing the
|
|
same interface.
