I came across a boat load of these the other day. Seems fairly naff that
we substitute variables blindly.
Seems like we could be slightly more friendly without too much bother:
at least only substitute after the VALUES clause in INSERT. We really
shouldn't substitute "var = var" to "$n = $n" either; am I right in
thinking the latter would happen silently and cause potential error?
