+Internally, Grid defines a portable abstraction SIMD vectorisation, via the following types:
+
+* `vRealF`
+
+* `vRealD`
+
+* `vComplexF`
+
+* `vComplexD`
+
+These have the usual range of arithmetic operators and functions acting upon them. They do not form
+part of the API, but are mentioned to (partially) explain the need for controlling the
+layout transformation in lattice objects.
