supertypeinformation attached to every error in Language.C
converts an error into a string using a fixed format
either the lines of the long error message or the short message has to be non-empty
the format is
<fname>:<row>: (column <col>) [<err lvl>]
>>> <line_1>
<line_2>
...
<line_n>error raised if a operation requires an unsupported or not yet implemented feature.
