[I7-1528] [Mantis 1564] Sentence verb fails for a property of a KOV

[curiousdannii-testing]

Reported by : zarf

Description :

In the code below, the first test works correctly. The second one triggers a run-time error:

Yes (1).

[** Programming error: tried to find the "." of (something) **]
[** Programming error: tried to read (something) **]

Steps to reproduce :

The Kitchen is a room. 

A material is a kind of value. The materials are metal, ceramic, and polymer.
A resistance is a kind of value. The resistances are brittle, hard, and soft.

A material has a resistance called the stiffness.

The verb to feel means the stiffness property.
Metal feels hard. Ceramic feels brittle. Polymer feels soft.

When play begins:
    if the stiffness of metal is hard:
        say "Yes (1).";
    if metal feels hard:  [this test compiles wrong]
        say "Yes (2).";

Comment by zarf :
In the generated I6, you can see that the compiler is using object property syntax (x.y) even though metal is a KOV.

    ! [1: if the stiffness of metal is hard begin]

    if (((GProperty(52, I126_metal,p15_stiffness) == I131_hard)))

{
! [2: say ~Yes (1).~]
say__p=1;ParaContent(); print "Yes (1)."; new_line; .L_Say1; .L_SayX1;
! [3: end if]
}
    ! [4: if metal feels hard begin]

    if (((I126_metal.p15_stiffness == I131_hard)))
{
! [5: say ~Yes (2).~]
say__p=1;ParaContent(); print "Yes (2)."; new_line; .L_Say2; .L_SayX2;
! [6: end if]
}
