Confused about storing arrays in a custom property

[Pete]

I read in the LC manual that it isn;t possible to store an array in a single
custom property, yet I have done that and it seems to work fine.  The
Inspector doesn't show the value, just a greyed out message about it being
an array.

Before I go any further down that path, is this a safe thing to do?
