will assigning variable change the inner value ?

xiaoyafeng has asked for the wisdom of the Perl Monks concerning the following question:

Hi monks,

Why the stuff printed as below is different?

     root@xyf-laptop:~# perl -e ' print getpwuid($<);'
root$6$J0bTOS1H$lnxARf6GOL5rPmGIuYR4IkFBbANmrTeSaIj8BrCehOkftUB2xjPbxq

+# 
root@xyf-laptop:~# 
root@xyf-laptop:~# perl -e ' $a = getpwuid($<); print $a;'

`getpwuid()` returns different results depending on whether it's called in list context (as with `print`), or in scalar context, i.e. `$a = ...` Try `$ perl -e '@a = getpwuid($<); print @a;'` [download]	[reply] [d/l] [select]
