post	Released Cyclone Scheme 0.7.2	Cyclone now includes a built-in pattern match library! This release also provides bug fixes for macro hygiene and allocation of large objects.

Features

• Added a (scheme cyclone match) library based on Alex Shinn's match.scm portable hygienic pattern matcher.
• The compiler now emits a faster version of apply in cases where only two arguments are received.

Bug Fixes

• Made several improvements to macro hygiene by renaming local variable bindings during expansion. Added a unit test module covering many test cases.
• Fixed many functions including utf8->string, string->utf8, bytevector-copy, list->vector, and list->string to heap allocate objects that exceed the maximum size for objects on the stack.
• Prevent a compiler error when there is only one argument to + or *.
