Can be newest completions used with e.g. 5.0.2, or 4.x

[Sebastian Gniazdowski]

Hello,
I will test this, but an information about what changes in Zsh can
influence completions' backward compatibility would be useful. I
recall one thing, the ability to do =() right after typeset -a. If one
person uses this in current completion, it will not be backward
compatible. Any more such things?

Best regards,

The ${(b)foo} syntax has been added.

The _cmdstring completion function has been added.

Some completion library functions have received bugfixes (_arguments) or
new features (_describe).

There might be new builtin parameters, but I don't recall one aimed at
completion functions specifically.

Cheers,

Daniel

Eh, I thought that things like typeset -a*=() will be easy to convert
to traditional syntax in name of robustness. Code that runs on any
version, like z-sy-h, that runs on 4.3.9. But (b) can be added in the
name of robustness too. Code that doesn't break in edge cases.

This can be simply copied to previous Zsh version?

That also can be copied.

That would be problematic.
