Hello Vim developers,
In a plugin, I want to avoid that a :put =var command clobbers the expression
register, so I save this via getreg('=', 1). I realized that I couldn't use
setreg() to restore the expression register, but assignment via :let @= = var
works just fine. Is this disallowed for setreg() because both the "append to
register" functionality and the regtype argument don't make sense here?
I think it would be helpful to hint at the possibility of using :let @=;
otherwise, people might assume that restoring the expression register value
isn't possible at all.
