Previously, a struct (anonymous or named) whose fields all matched the
predicate would not be sharded and would simply be reused. However,
that could break the maxNameSize limitation which could cause problems
for the caller.
This change makes sure that the supplied struct is only reused if it
does not exceed the maxNameSize, and otherwise is sharded.

Blueprint is a meta-build system that reads in Blueprints files that describe
modules that need to be built, and produces a
Ninja manifest describing the commands that
need to be run and their dependencies. Where most build systems use built-in
rules or a domain-specific language to describe the logic for converting module
descriptions to build rules, Blueprint delegates this to per-project build
logic written in Go. For large, heterogenous projects this allows the inherent
complexity of the build logic to be maintained in a high-level language, while
still allowing simple changes to individual modules by modifying easy to
understand Blueprints files.
