syntax_error(+Culprit)

A text has invalid syntax. The error is described by Culprit. According to the ISO Standard, Culprit should be an implementation-dependent atom.

To be done: Deal with proper description of the location of the error. For short texts, we allow for Type(Text), meaning Text is not a valid Type. E.g. syntax_error(number('1a')) means that 1a is not a valid number.
