It is difficult -- not simple -- to write perfect conversions.  The 
"AsMoment" properties allow a simple renaming as a backup when preferred 
conversions are missed.

For many of these properties, it was not a simple task to clean up 
LilyPond's internal Scheme code.  Adding the deprecated properties was 
an errand of mercy to users facing something similar.  Their old 
calculations should work unchanged with the "AsMoment" properties, 
allowing time to rework them to use plain old numbers instead of ly:moments.
