only FYI: just thinking it could be helpful to have constants or aliases for your log levels so it's easier to know what is verbose or error etc very quickly when looking at the code

like .log ${TRACE} .log ${INFO}
or aliases
.log:trace "Read PATH env: $PATH"`` trace "Read PATH env: $PATH"``

Yep, also thought about it. Because there are a lot of log messages and they needs to be organized for readability. Will provide such improvements in next PR.
