LambdaMessageSend

• SqueakL + MIT - Dual licensed under both SqueakL and MIT. This enables both base Squeak inclusion and 100% reuse. Recommended prior to 4.0.
• Only extensions, no changes - Code extensions but no changes in existing code.
• Not backwards compatible - Code has changed and breaks compatibility for sure.
• Squeak3.8 - Released 25 May 2005.
• Squeak3.9 - Released 8 Dec 2006.
• Beta - Useable but still not stable, probably has bugs.
• Non official package - Just a package for Squeak, no community guarantees. :)
• Simple filein - A '.st' or '.cs' (changeset) standard filein. Optionally gzipped with extra extension '.gz'.

code cleanup, bug fixes

improved reduction algorithm (with notably proper alpha conversion)

it is now quite easy to do actual lambda calculus:
see for example FunctionalTalkTest #testChurchNumerals
