usefulness of 'also'

[fhein]

I was thinking, is the new function 'also' really useful? Can it do anything that a simple parenthesis can't?

Ie

a: also 1 print "a"

appears to do the same as

a: (print "a" 1)

Do you find the also-syntax more readable? Maybe if the additional stuff is really long, and you want the assigned value close to the set-word?

Absolutely useful.  It can save having to use temporary variables when traversing series (for one of many uses).

d: first s  s: next s  d

  can now be 

also first s s: next s

But 2.7.6 also includes first+  so that example is already 'out of date'. 

first+ s

And looking at the source for also opens up all kinds of potential for selective evaluation.   Need the first result of three?

three: func [arg1 [any-type!] arg2 [any-type!] arg3 [any-type!]] [get/any 'arg1]

Want the second of four  just add an arg4 and get/any 'arg2.

The classic example is:
