Here, I meant "scripts " is "script files" whether they contains a series of
commands, or reusable functions.
This practice is not based on other replies, not yours.

If the script files is a collection of functions, as you said, creating a
package can be one solution.

Why are there no additional steps?
You suggested creating and installing a package is the solution to source
frequently used functions.
Then, every time I add/modify a function in a script file, or add new script
file, I have to re-create and re-install the package,
which are additional steps, not directly related with the addition or
modification.

More fundamental problem here is that the functions may have no common
context except "frequently used".
In the case, bundling all the functions into one package may not be a proper
choice.

So, I still think creating new package mayb be too heavy solution.
Why don't we simply extend a little bit the searching range of source
function?
