We already have partition() functions that actually partition a
range into two subranges, so adding partitionBy with a
different meaning may be confusing. -- Andrei
In ruby, the closest to D's currently-named groupBy method is a
set of three methods:
slice_before
slice_after
slice_when
http://ruby-doc.org/core-2.2.0/Enumerable.html#method-i-slice_when
Your example in ruby would be:
2.2.0 > [293, 453, 600, 929, 339, 812, 222, 680, 529,
768].slice_when { |x,y| x & 1 != y & 1 }.to_a
=> [[293, 453], [600], [929, 339], [812, 222, 680], [529], [768]]
