Older residents have claimed that formerly close-knit communities such as Easton have been shut off by the imposing concrete barriers next to the motorway.

M4 (computer language) FreeBSD, NetBSD, and OpenBSD provide independent implementations of the m4 language. Furthermore, the Heirloom Project Development Tools includes a free version of the m4 language, derived from OpenSolaris. "GNU m4" is an implementation of m4 for the GNU Project. It is designed to avoid many kinds of arbitrary limits found in traditional m4 implementations, such as maximum line lengths, maximum size of a macro and number of macros. Removing such arbitrary limits is one of the stated goals of the GNU Project. The GNU Autoconf package makes extensive use of the features of GNU m4. GNU m4 is currently maintained
