You defined the envrionment variable sample_text BEFORE you decalred the function, so it already had the variable defined.

General::Interpolated(3) User Contributed Perl Documentation General::Interpolated(3)NAME
Config::General::Interpolated - Parse variables within Config files
SYNOPSIS
use Config::General;
$conf = new Config::General(
-ConfigFile => 'configfile',
-InterPolateVars => 1
);
DESCRIPTION
This is an internal module which makes it possible to interpolate Perl style variables in your config file (i.e. $variable or
"${variable}").
Normally you don't call it directly.
VARIABLES
Variables can be defined everywhere in the config and can be used afterwards as the value of an option. Variables cannot be used as keys or
as part of keys.
If you define a variable inside a block or a named block then it is only visible within this block or within blocks which are defined
inside this block. Well - let's take a look to an example:
# sample config which uses variables
basedir = /opt/ora
user = t_space
sys = unix
<table intern>
instance = INTERN
owner = $user # "t_space"
logdir = $basedir/log # "/opt/ora/log"
sys = macos
<procs>
misc1 = ${sys}_${instance} # macos_INTERN
misc2 = $user # "t_space"
</procs>
</table>
This will result in the following structure:
{
'basedir' => '/opt/ora',
'user' => 't_space'
'sys' => 'unix',
'table' => {
'intern' => {
'sys' => 'macos',
'logdir' => '/opt/ora/log',
'instance' => 'INTERN',
'owner' => 't_space',
'procs' => {
'misc1' => 'macos_INTERN',
'misc2' => 't_space'
}
}
}
As you can see, the variable sys has been defined twice. Inside the <procs> block a variable ${sys} has been used, which then were
interpolated into the value of sys defined inside the <table> block, not the sys variable one level above. If sys were not defined inside
the <table> block then the "global" variable sys would have been used instead with the value of "unix".
Variables inside double quotes will be interpolated, but variables inside single quotes will not interpolated. This is the same behavior as
you know of Perl itself.
In addition you can surround variable names with curly braces to avoid misinterpretation by the parser.
