Description
This improves the performance of the idx functions which return the global index (e.g. iglo in the g_lo layout) from the dimensional indices (e.g. it, ik, il, ie, is). We do this by replacing the (slow) select case(layout) structure with a single expression that applies for all layouts.
According to the indexing benchmarks in PR #171, this change speeds up indexing currently in next by about 40%. [Sigh. Table doesn’t render.]
