I just noticed that compiling the package code at

)abbrev package MYEXP MyExp
MyExp(F: Algebra(Fraction(Integer))): with
myexp: F -> F
myexp: (F, NonNegativeInteger) -> F
== add
Map2 ==> ListFunctions2(NonNegativeInteger, F)
myexp(x, n) ==
a(i : NonNegativeInteger) : F == (1/(factorial i)) * x^i
reduce(_+@((F, F) -> F), map(a, [i for i in 0..n])$Map2)
myexp(x: F): F == myexp(x, 32)

Gives the following error message:
>> System error:
The bounding indices 163 and 162 are bad for a sequence of length 162.
