A better solution is just to use the word 'lambda', and let your text editor render it as a lambda symbol if you want (my emacs does this).

No, that's a shithouse solution.

Everyone that doesn't have a fancy IDE now has 6-8 extra useless characters for something that should be syntax.

How is it different than the word "function"?

[BigJono]

It's not, that's why people use arrow syntax in languages like Javascript for short in-lined functions.
