Not necessarily to be avoided, so much as a hint that you _must_ use
#!/bin/bash rather than #!/bin/sh to run the script (I welcome the full
power of bash, once I've conceded that I will always be running the
script under bash).  I merely point out bashisms as a service to help
readers of this list decide which shell they really meant to be using,
and to make them think about whether they intend to be portable to other
shells or if they are okay being locked into bash extensions.
