Lambda functions timeline

I did a talk at work about lambda functions (anonymous functions), and something possessed me to make a timeline of when they were introduced into various languages. Some languages were born with them, and some grew them later - in the latter case I give the language version and date in which they were introduced.

It's probably entirely wrong, but here it is:

Note that C# had varying levels of support for lambda functions in different versions. I used the version (3.0) in which Wikipedia describes its support as "full".
