Description
At the debugger prompt, syntax with chained comparison operators is incorrectly parsed in some cases when constants are used.
Steps to Reproduce
DB<1> x ( 1 < 2 < 3 )
0 2
1 1
DB<2> @ex = ( 7 < 8 < 9 )
DB<3> x @ex
0 8
1 1
DB<4> $rr = 8
DB<5> x ( 7 < $rr > 9 )
0 8
1 ''
DB<6> x ( $rr < 8.5 < $rr+1 )
0 1
DB<7> x ( $rr < 8.5 < 9 )
0 8.5
1 1
DB<8> x ( 9 > $rr > 7 )
0 8
1 ''
DB<9> x ( 9 >= $rr >= $rr-2 )
0 1
DB<10>
Expected behavior
Perl source files with this new syntax are processed as expected, and should work the same at the debugger prompt.
