If we want to avoid typing out "Range", we can just define "R" as Range.
Then we can do this with:

Graphics[
 Line[{{0, 10 - #}, {#, 0}}] & /@ 0~R~10
 ]

It looks like the ampersand will apply to the whole Line[ ] expression
without having to parenthesize it.

What I'd really like to do is have a more intuitive expression such as the
ellipsis character, =8A, for Range, and to be able to use it the way "+" and
"-" are used, without having to type the tildes on either side to show it's
an infix symbol.

At any rate, here it is with the ellipsis defined as Range:

\[Ellipsis] = Range

Graphics[
 Line[{{0, 10 - #}, {#, 0}}] & /@ 0~\[Ellipsis]~10
 ]
