If you want to omit characters, you can write

my %hash = map $_=>1, qw(shave the modern way);
[download]

Interestingly, you can't. If you want to remove the block you need to have

map +($_ => 1), ...
[download]

as => is a comma, so what you actually wrote is equivalent to these two statements below.

my %hash = map $_, 1, qw(shave the modern way);
my %hash = map { $_ } 1, qw(shave the modern way);
[download]

(If you write map ($_ => 1), LIST the "function rule" kicks in and it becomes map($_ => 1), LIST i.e. (map $_, 1), LIST.)

This means that you can write

map f($_) => LIST
[download]

which one could read declaratively as "map the function f onto the list I'm pointing at". Personally though I usually think of map as acting in the other direction, "shifting" of one element at a time from the list.
