Some evaluation is done first:
perl -Mstrict -MData::Dumper -wle'
$_ = {0b1_0 => "A", 01_0 => "B", 0x1_0 => "C", 1_0 => "D", _1_0 =>
"E", *_ => "F", \_ => "G"};
print Dumper $_
'
$VAR1 = {
'8' => 'B',
'_1_0' => 'E',
'*main::_' => 'F',
'10' => 'D',
'16' => 'C',
'SCALAR(0x8062850)' => 'G',
'2' => 'A'
};
