Abstract

Rationale
TODO
Syntax and semantics
Instead of writing this:
MINUTES = 60 timeout = 20 * MINUTES
or this:
timeout = 20 * 60 # 20 minutes
we will write this:
>>> timeout = 20 min >>> print(timeout) 1200
This will also work nicely in terms of different units:
>>> timeout = 5 h + 20 min >>> print(timeout) 19200
More examples:
connect(buffer = 4K, ..) # 4096 sleep(1 min) # 60 TOKEN_TTL = 8h # 28800 MAX_WEIGHT = 7.5 kg # 7500
TODO: more real world examples
TODO: how this will work within string formatting
