in reply to Neat Debugger tricks

When I set a break point inside a loop and I want to track the value of one or more variables at each iteration, I find it saves a lot of time/tedium to use "< expression" -- like so:

DB<1> b 123 DB<2> < print "## $var1 ## $var2 ## $whatever ##\n" DB<3> c 123: some_line_of_code(); ## var1_value ## thisisvar2 ## and so on ## DB<4>
Naturally, you could put "print Dumper($whatever)" as well, or any other operation that might speed up the debugging inside a loop.
