| # Used in fold() to build change object | |

All variable names have been changed to protect the innocent. Likeness to any variables presently in or out of scope is purely coincidental.
Got caught by the following snippet this morning:
# given a heterogeneous array,
# I'm only interested in positive integers
# and I really only need one
first_positive_integer = array.reduce([]) do |memo, obj|
| // save current buffer | |
| streambuf* coutBak = cout.rdbuf(); | |
| // setup temp stream | |
| stringstream coutBuf; | |
| // redirect to temp | |
| cout.rdbuf(coutBuf.rdbuf()); | |
| // test against contents of coutBuf.str() |
