in the expression &$functionTable{'string_1'}(ARGLIST); the & operator
binds more tightly with $functionTable as a scalar than as a hash
access. try the syntax below, or better yet use the -> dereference
operator.
perl -wMstrict -le
"my %functionTable = (
string_1 => sub { print qq{one: @_} },
string_2 => sub { print qq{two: @_} },
);
&{ $functionTable{string_1} }(qw(a b c));
$functionTable{string_2}->(qw(x y z));"
one: a b c
two: x y z
