BashFAQ/024 (Why can't I pipe data to read?) - Greg's Wiki
So when you try to pipe into 'readarray', the variable you're trying to 'readarray' *into* is created in the context of the subshell, and then deleted when the subshell terminates.
The reason for this potentially surprising behaviour, as described above, is that each SubShell introduces a new variable context and environment. The while loop above is executed in a new subshell with its own copy of the variable linecount created with the initial value of '0' taken from the parent shell. This copy then is used for counting. When the while loop is finished, the subshell copy is discarded, and the original variable linecount of the parent (whose value hasn't changed) is used in the echo command.

Why Research Could Make or Break Your Journey Mapping Effort
Brilliant: Contrasts hypothesis v. #journey #maps, shows why many maps fail to deliver; they use internal data, NOT customer-centric unstructured data that's focused on JTBD. BTW, #Agile #Digital #Ethnography changes the game in journey research.

sh - Check if a file exists with wildcard in shell script - Stack Overflow | https://stackoverflow.com/
You can do the following:
<code class="language-bash">
set -- xorg-x11-fonts*
if [ -f "$1" ]; then
printf "BLAH"
fi
</code>

This works with sh and derivates: ksh and bash. It doesn't create any sub-shell. $(..)and `...` commands create a sub-shell : they fork a process, and they are inefficient. Of course it works with several files, and this solution can be the fastest, or second to the fastest one.

It works too when there's no matches. There isn't need to use nullglob as one of the comentatators say. $1 will contain the origintal test name, therefore the test -f $1 won't success, because the $1 file doesn't exist.

How to prevent overwritting Python Built-in Function by accident? - Stack Overflow | https://stackoverflow.com/
You can't. You could use linters (e.g. pylint) which will check for this kind of thing, but Python allows you to reuse anything except a keyword (https://docs.python.org/2/reference/lexical_analysis.html#keywords) or None.
You can't prevent it, Python is built on the notion of "we're all consenting adults" so you are free to do what you want. It is possible to delete the override but you'd have to know that you shadowed that function in the first place.
