Consider:

import std.regex, std.string;

void main() {
    split(s"hello", regex("[ \t,.;:?]+"));
}

The compiler complains:

test.d(5): Error: std.regex.split(String,RegEx) if (isSomeString!(String) &&
isRegexFor!(RegEx,String)) at /Users/aalexandre/code/d/phobos/std/regex.d(6796)
conflicts with std.string.split at
/Users/aalexandre/code/d/phobos/std/string.d(70)

However, line 60 in std.string just aliases split to std.array.split. In turn,
std.array defines two split functions, neither of which accepts a regex in the
second position. So there is no potential hijacking.
