🐞 Shorthand assignment operator `+=` is not supported by Bash 2

[Ph0enixKM]

We could add a flag --out-version=X in scope of this issue to determine which bash version output should be produced to keep outputted Bash be the most readable possible. By default we'd support Bash 2.

--out-version=3

arr+=("value")

--out-version=2

arr=("${arr[@]}" "value")

Also we could replace seq in range generation for Bash 3 with {a..b} syntax. Example syntax:

--out-version=3

{0..10}

--out-version=2

seq 0 10

wouldn't that mean that we'd have to reimplement translator for each bash version? kinda seems like overkill for me

[Ph0enixKM]

Nope. We could get the version in the syntax module

[Ph0enixKM]

I can create a draft to better visualize this. Bash version 3 isn’t a different language. We could just determine if translating one syntax formula can lead to a bit different representation in resulting Bash.
