I investigated a little further bug #359. Thanks to a helpful anonymous, we
can now trigger it simply by saying
(1) -> eq := 1=1
(1) 1= 1
Type: Equation PositiveInteger
(2) -> )se bre bre
(2) -> [eq::Boolean]
(2) [true]
Type: List Boolean
(3) -> [eq::Boolean for i in 1..1]
Internal Error
Generated code is incorrect for equation
Break.
Broken at |UPCOLLECT|. Type :H for Help.

[coerce(eq)@Boolean for i in 1..1] works, by the way, [(1=1)::Boolean for i in
1..1], too. upCollect and upconstruct are defined in i-spec1.boot.pamphlet.
The only location where this error message is thrown is in coerceByFunction in
i-coerce.boot.pamphlet, the error code is S2IC0015.
I tried to read upconstruct, upCOLLECT and coerceByFunction, but I have no idea
what they are doing. In fact, I don't even see how upconstruct calls upCOLLECT
and coerceByFunction.
