Usage

 use SHARYANTO::Scalar::Util qw(
     looks_like_int
     looks_like_float
     looks_like_real
 );
 say looks_like_int(10);              # 1, isint() also returns 1
 say looks_like_int("1".("0" x 100)); # 1, isint() returns 0 here
 say looks_like_int("123a");          # 0
 say looks_like_float(1.1);           # 1
 say looks_like_float("1e2");         # 1
 say looks_like_float("-Inf");        # 1
 say looks_like_float("");            # 0
 # either looks like int, or float
 say looks_like_real(1);              # 1
 say looks_like_real(1.1);            # 1
