You might be able to hack something from my "Regular Expression Matcher",
found in the Euphoria archive. It's aimed at LEX-type expressions, but it's
not that far from what you are aiming for.

Try instead:

  result = regex("^\\(d).?\\1$", myVar)

You need quotes {"} instead of faces {{}}, or Euphoria will try to evaluate
your expression. In addition, the backslash {\} is a poor selection in
Euphoria. It is used to delimit special characters, like

    \t (tab)
    \n (new line)
    \r (carriage return)
    \" (quote)
    \' (single quote)
    \\ (backslash).

Same problem as above:

  x = "m5439'.e5588/#s...-*\''s009989/&a785784g4654677,,.^^\(((~~e"
