/**
 * JSON does not support regexes, so, e.g., JSON.parse() will not create
 * a RegExp from the JSON value `[ "/matchString/" ]`, which is
 * technically just an array containing a string that begins and end with
 * a forward slash. To get a RegExp from a JSON string, it must be
 * constructed explicitly in JavaScript.
 *
 * The likelihood of actually wanting to match text that is enclosed in
 * forward slashes is probably quite rare, so if forward slashes were
 * included in an argument that requires a regex, the user most likely
 * thought they were part of the syntax for specifying a regex.
 *
 * In the unlikely case that forward slashes are indeed desired in the
 * search string, the user would need to enclose the expression in a
 * second set of slashes:
 *
 *    --customAttrSrround "[\"//matchString//\"]"
