Subject: Problem with "here" document in hash constructor?

In the following code example, constructing hash1 works fine,
but constructing hash2 gives me a hash with only one key:

###########################################################
hash1 = {
    "key1"      => "value1" ,
    "key2"      => "value2"
}

p hash1
p hash1.keys.length

hash2 = {
"key1" => <<EOF
value1
EOF,
"key2" => <<EOF
value2
EOF
}

p hash2
p hash2.keys.length
########################################################

If I move the comma separating the two key/value pairs
to its own line (so that EOF is recognized properly), I get
a syntax error:

T2.rb:17: syntax error
T2.rb:18: warning: useless use of a literal in void context
T2.rb:18: syntax error
"key2" => <<EOF
         ^

Is there any way to do this using "here" documents (<<EOF)
and the Hash {} constructor style?  I know I can do it by
constructing the hash another way, but...

Thanks,

JA
