Version 289 is out.

Hi all,

TXR 289 is out.

Binaries in usual location.

Some rare events are coinciding in this release.

• the hash table implementation changes to open addressing (with linear probing).
• integers and ranges can be usefully called as functions now.
• the TXR Pattern Language gets a new directive @(push), previously discussed and included in an interim release.

Some important bugs are fixed, including an instability caused by the ssort-function, when the argument is a vector, and an unfortunate incorrectness in the equal function with regard to equality substitution.

Cheers ...
