<h2>Computational class</h2>
It is believed to be Turing-complete, because a [http://esolangs.org/wiki/Tag_system|tag system] can be implemented, for example:
<verbatim-1>
{define "skip" {call \2}}
{define "1" {skip \1|"3"|"3"|"2"|"1"|"H"}}
{define "2" {skip \1|"3"|"3"|"1"}}
{define "3" {skip \1|"3"|"3"}}
{define "H" \1}
{call "2"|"1"|"1"}
</verbatim-1>
