Version 0.6.1

Bugfix:

• Catch UnknownArity in all modules that use unpythonic.arity.arity_includes().

Version 0.6.0

New and improved sequencing constructs.

• Rename the v0.5.1 do --> pipe
• Add piped, lazy_piped for shell-like pipe syntax
• Add a new do: an improved begin that can name intermediate results

Version 0.5.1

• Catch more errors in client code:
  • Validate arity of callable value in letrec (both versions)
  • Validate callability and arity of body in all let constructs
  • In env, require name to be an identifier even when subscripting
• Add flag to enable_fasttco() to be able to switch it back off (during the same run of the Python interpreter)
• Internal enhancement: add unit tests for env

Version 0.5.0

• Make the TCO implementation switchable at run time, see enable_fasttco().
• Default to the slower exception-based TCO that has easier syntax.

Version 0.4.3

• Print a warning for unclaimed TCO jump instances (to help detect bugs in client code)

Version 0.4.2

• fix install bug

Version 0.4.1

• Export unpythonic.misc.pack
• Update description for PyPI

Version 0.4.0

• First version published on PyPI
• Add @breakably_looped, @breakably_looped_over
• Rename @immediate to @call; maybe the most descriptive short name given call/ec and similar.
