Our inplace idiom occurs warning like warning: possibly useless use of + in void context.
To avoid such warnings, how do you think defining inplace=?
With this method, we can write ary.inplace += 10, which don't occur such warnings.
$ cat -n inplace.rb
1 require 'numo/narray'

3 class Numo::NArray

5 def inplace=(other)
6 self

10 a = Numo::DFloat[1, 2, 3, 4, 5]
11 a.inplace + 10 # this involves a warning
12 a.inplace += 20 # this doesn't involve a warning
$ ruby -w inplace.rb
