I was thinking of the time I calculated IPV6 EUI64 suffixes in bash for a kind of janky IPAM thing, and how even the barest minimum of arithmetic turned “instantaneous” into “takes seconds”. The bash-centric solution was to write a little eui64.c and call that from the script. Bash isn’t for doing things, it’s for making other programs do things. That worked fine for a bit, but in the end it just became easier to factor and reason about the project when it wasn’t a weird mixture of clever things, and one Pythonic lump of boring and predictable things.
