I disagree. `&` is known to invoke `to_proc` and place the result in the
block slot, and Symol#to_proc is known to be `->(obj) { obj.send self }`
(or some equivalent). This is everywhere in Ruby, every method has a block
slot, and you can put any block into it with the ampersand. The
`map(:strip)` by contrast is it's own pattern, the only other place I've
seen it is in `sum = numbers.reduce(0, :+)`
Also, it means the dev is disassociating themselves from the functional
paradigm, which means other relevant uses will be less mentally accessible
e.g. `filenames.map &File.method(:read)`

It is better that they learn about it than hide from it. Methods have a
magic block slot, Rubyists need to know this and know how to use it.
This makes me think of when I didn't understand the `$LOAD_PATH`, because
Ruby <1.9.2 included "." in it. Sure it made it easier for newbies like me,
but it left a huge gap in my understanding that caused numerous problems
until I eventually figured it out when moving to latest rubies where I had
to deal with it.
Just look at it again to compare:

I don't think the `&` is syntactic sugar. You could say `a + b` is
syntactic sugar for `a.+(b)`, but what is `lines.map! &:strip!` syntactic
sugar for?
As an aside, this, brings up that this code is buggy. Since strip! modifies
the string, there is no need for map. Especially considering that strip! is
expected to be used by modifying the string, not relying on its return
value (which I think is much more egregious than using `&` to access the
block slot), so it's return values are not consistent:
lines = %W[line1\n line2]
lines.map! &:strip!
lines # => ["line1", nil]
To avoid this bug, use `lines.each &:strip!` Which brings up the point, if
you change map such that you can `lines.map! :strip!` then realize you need
to use the each form, `lines.each :strip` will not work. This is
inconsistent (and changing `each` is impractical as it is implemented on
each collection rather than being inherited from Enumerable) but `&:strip`
will, again, work everywhere.

I keep warnings off, I would write `.each &:strip!` (or, more probably

Methods ending in ! are exactly the same as methods that don't end in !.
Any differences are just convention, and the conventions around it are so
inconsistent that they're practically meaningless. So this is like saying
"they need to understand methods containing underscores" when talking about
`to_s`
