Hello again,

While working with your code, I noticed that you use 3 different R files to launch R lambdas...

At first I was a bit puzzled by the contents of bootstrap.R:

source('/var/task/runtime.R')
# TODO: Why the multiple initializeRuntime()?
tryCatch({
    function_name <- initializeRuntime()
    while (TRUE) {
        handle_request(function_name)
        logReset()
        rm(list=ls())
        source('/var/task/runtime.R')
        function_name <- initializeRuntime()
    }
}, error = throwInitError)

Could you please elaborate on why are there multiple initializeRuntime() and the use of the while(TRUE)? Did you face some operational issues if you didn't do it this way?

In my mind, runtime.R is appropriate to bundle some utility functions but I'm a bit confused by the code above and why not include the custom code/function into bootstrap.R itself instead of having functions.R?

Also, how would you expand your example to accept incoming parameters such handling S3 events?
