That, and more... I want all

??      (one-time matching) syntax: ?PATTERN?
m//     (matching) syntax: m/PATTERN/gimosx
//      (matching) syntax: /PATTERN/gimosx
q//     (single/direct quoting, maybe unnecessary) syntax: q/STRING/
qq//    (double/interpolated quoting, will substitute embedded vars etc)
        syntax: qq/STRING/
qx//    (backquoting: execute, and return stdout) syntax: qx/STRING/
qw//    (list of words, can be simulated quite easily in Euphoria)
        syntax: qw/STRING/
s///    (substitution) syntax: s/PATTERN/REPLACEMENT/egimosx
        e.g. s/do/did/g used on "Can we undo what he does?"
        will give you "Can we undid what he dides?"
tr///   (translation) syntax: tr/SEARCHLIST/REPLACEMENTLIST/cds
y///    (translation) syntax: y/SEARCHLIST/REPLACEMENTLIST/cds

tr/// = y///
m// = //
