* Create a new {@link Profiles} instance that checks for matches against

* <p>The returned instance will {@linkplain Profiles#matches(Predicate) match}
* if any one of the given profile strings matches.
* <p>A profile string may contain a simple profile name (for example
* {@code "production"}) or a profile expression. A profile expression allows
* for more complicated profile logic to be expressed, for example
* {@code "production & cloud"}.
* <p>The following operators are supported in profile expressions.
* <ul>
* <li>{@code !} - A logical <em>NOT</em> of the profile or profile expression</li>
* <li>{@code &} - A logical <em>AND</em> of the profiles or profile expressions</li>
* <li>{@code |} - A logical <em>OR</em> of the profiles or profile expressions</li>
* </ul>
* <p>Please note that the {@code &} and {@code |} operators may not be mixed
* without using parentheses. For example {@code "a & b | c"} is not a valid
* expression; it must be expressed as {@code "(a & b) | c"} or
* {@code "a & (b | c)"}.
* <p>As of Spring Framework 5.1.17, two {@code Profiles} instances returned
* by this method are considered equivalent to each other (in terms of
* {@code equals()} and {@code hashCode()} semantics) if they are created
* with identical <em>profile strings</em>.
* @param profiles the <em>profile strings</em> to include
* @return a new {@link Profiles} instance
