An intuitive language should work as expected, in a consistent way. The learning curve is flattened if a pattern learned in one command or situation can be applied in another.
All types of containers (variables, files, global properties, and even chunks of other containers) can be treated alike, using the same commands and operators.
add one to count -- increment a variable
add one to line two of file "/tmp/scores" -- increment a chunk of a file
add one to the readTimeout -- increment a global property
