I think that most people agree that the := should be used instead of a left arrow in code.

To use the left arrow, get a fine-tipped permanent marker and very carefully draw an arrow head on the '_' key on your keyboard. Then, you can use this key for when you want a left arrow in your code. You may need to choose a font that has a left arrow in it as well.

If you want to get fancy (and I encourage you to do so for education's sake :-) ), you could try mapping the underscore key to output a left arrow character (←, Unicode 0x2190) using whatever your operating system provides, and then modify the Squeak compiler to use that for modification.
