yes, coding guidelines help a lot
i have some unusual preferences in that for my own projects because i get intensely curious about neat things i see... like, almost nobody else except a few smart guys know that you can do one line functions in Go, or that you can break lines after dot operators, and my current little thing is using a script to drop a "common" file into every package that gives you lots of handy type aliases and a few common functions that you can update just by changing one version and running a script
like, why would i type []byte when i could just use B
and in local scopes, who uses B anyway? that's an exported variable name, in a local scope? yes! that's the point, you aren't going to mistake it and why write []byte when you can write B!
it also injects loggers and such into the code, and honestly i think it would be a great feature in Go if you could write one file at the root of a repo that automatically is part of every package for this kind of stuff, it's not a macro system, it's aliases, and the aliases make the code more readable and easier to type
anyway, going off track, but JSON doesn't forbid JSON inside strings except that the quotes have to be escaped, pretty much, probably some shortcuts can be taken for this... as it is, i already experimented with this because tags are "free form" but there is a whole bunch of rigid structures defined and in many cases they use hex encoding which is automatically double the binary version and for runtime why the fuck deal in encodings when you match faster on the binary and if the binary is what your database uses???
but it's work that i'm doing because of my own personal distaste for convention and love of elegance and conciseness
in my own work, this leads to me recognising bugs in my code faster because i spend less time ignoring fluff and more time actually understanding the code
there is some hilarious morons who like to chant "the code is the documentation" but you read their code and it's like reading beat poetry, good luck making sense of it, and the time it takes for the compiler to turn it into assembler... that's a big hint that the code is unclear
