UFCS vs auto-completion support

[Jay Norwood via Digitalmars-d-learn]

I'm reading Jack Stouffer's documentation:
http://jackstouffer.com/blog/nd_slice.html

considering the UFCS example below and how it would impact 
auto-completion support.

auto slice = sliced(iota(1000), 5, 5, 40);

auto slice = 1000.iota.sliced(5, 5, 40);

Seems like auto-complete support for the second form would be 
complicated.  Do any of the auto-completion implementations even 
attempt to support that second form?
