Lilypond currently supports simple "irrational meters" like 4/10, 7/6, etc.  
which are used by contemporary composers such as Ferneyhough, Adčs, etc.

However, \compoundMeter cannot handle many of these complex notations.  It  
sometimes fails when an irrational component such as 1/10 is included in  
the compound meter, and fails when a _fractional_ value such as 2/3 is  
included in the compound meter -- as in Boulez' "Le marteau sans maître"  
where there are time signatures such as (4 + 2/3)/8 .

I've attached 3 minimal examples, 2 which fail with the compound meter but  
compile with the equivalent non-compound irrational meter; and one which  
includes a compound irrational meter that works.
