After reading your comment, I went through my most commonly used apps and found that they all have a hamburger button in the top left corner that brings up the same menu as a swipe from left gesture. Somehow I never noticed those buttons before, leaving me feeling a bit spooked. How is it that something I look at dozens of times a day could go unnoticed for so long?

I had the inverse reaction: I discovered that all these apps support swiping from the left. At least the hamburger menu is visible - there is nothing really advertising the swipe gesture.
