In this example:
p := &[]int{}
append([]int{}, *<>)
At <> we completed to "**p" instead of "*p...". There were two fixes:
1. builtinArgType() wasn't propagating the "modifiers", so we were
forgetting about the preceding "*" pointer indirection and
inserting it again with the completion. Fix by propagating
modifiers.
2. The candidate formatting responsible for adding "..." had over
simplified logic to determine if we are completing the variadic
param. Now instead the candidate evaluation code marks the
candidate as "variadic" so the formatting doesn't have to think at
all.
