Following on from this, AAChange has the following two methods:
add_Allele() and allele_mut()

It appears that allele_mut is only capable of remembering 1 allele at a
time, whereas add_Allele() is provided to add support for mutliple
alleles - is that correct?

However, add_Allele() also calls allele_mut(), such that mutliple calls
to add_Allele will result in the overwriting of the allele being
remembered by allele_mut(). Things are further complicated by the fact
that label() uses allele_mut() to decide on the label to return.
Shouldn't label know aout multiple alleles set by multiple calls to
add_Allele?

It may be my lack of understanding alleles and what these classes are
intending to do, but trying to rewrite the test scripts to improve code
coverage has let me a little confused!

Thanks
Nath
