I've always wanted something like this!!!! but I think the proposed 
syntax might not fit very well with the D grammar.

hmm, come to think of it, maybe it can already be implemented with 
templates.

so,

if( x == 10 || x == 20 || x == 30 )

becomes:
if( equals!(x).anyOf( 10, 20, 30 ) )

or something like that!

any template guru up to it?

On a side note: the expression( x == 10 && x == 20 && x == 30 ) is 
rediclious, it's always false ;)
