Re: fatal error: module qualification is not allowed for the head of a clause (A:B)

[Daniel Diaz]

Hello,

In 1.4.0 there is a pre-support for modules. The compiler already recognizes : as module prefix operator (even if modules are not yet handled).

The simplest way consists in avoiding the : operator. 

Sorry

Daniel

I installed gprolog 1.4.0 and all went well.  However, I get a failure for a predicate which has the name ':' which is a the colon character as I had used this predicate to define its behavior as an operator although at the time of the compile it is not declared as an operator.  The failure message is below.

I looked through the NEWS file for the new release but I cannot see anything in the list which seems to apply.
