sometimes we have some big expressions that get some members of an object like tree->ancestor->son->sibbling->...->bla->bla its annoying to always have to do like 

if(
( tree->ancestor->son->sibbling->...->bla->bla eq "john") or
( tree->ancestor->son->sibbling->...->bla->bla eq "Mary")
)

is there a way of expressing something like: 
if ( expression is_in (val1,val2,val3) )

[download]
it would be very helpful
