The existing standalone Query function builds an importer, ssa.Program, oracle,
and query position, executes the query and returns the result.
For clients (such as Frederik Zipp's web-based github.com/fzipp/pythia tool)
that wish to load the program once and make several queries, we now expose
these as separate operations too. Here's a client, in pseudocode:
o := oracle.New(...)
for ... {
qpos := o.ParseQueryPos(...)
res := o.Query(mode, qpos)
print result
}
NB: this is a slight deoptimisation in the one-shot case since we have to
build the entire SSA program with debug info, not just the query package,
since we now don't know the query package at that time.
The 'exact' param to ParseQueryPos needs more thought since its
ideal value is a function of the query mode. This will do for now.
Details:
- expose Oracle type, New() func and Query() method.
- expose QueryPos type and ParseQueryPos func.
- improved package doc comment.
- un-exposed the "needs" bits.
- added test.

This subrepository holds the source for various packages and tools that support the Go programming language. Although at least some of the tools themselves will be included in binary Go distributions, the packages from which they are built are of little interest to most Go programmers. To submit changes to this repository, see http://golang.org/doc/contribute.html.
