Re: localtime array slice problem

#!/usr/bin/perl -w

use strict;


my @List=(localtime)[1,3];
print @List;

result: 3311

your code with 'use strict':

Ambiguous use of @{localtime} resolved to @localtime at ./tmp line 6.
Global symbol "@localtime" requires explicit package name at ./tmp lin
+e 6.
Execution of ./tmp aborted due to compilation errors.

Start with using strict... build from there, it will tell you
when you are REALLY messing up

Good point about trying new things out inside of a script with warnings and use strict on. In this case, since I already knew that localtime is a function, I was able to use the following to get right past both -w and use strict: `#!/usr/bin/perl -w use strict; print @{localtime()}[1,3]; 1;` [download] Running this as `perl -c ltimetest.pl` [download] checks out okay, but running it tells me that I "Can't use string ("Thu Jan 11.... as an ARRAY ref while in strict subs..." Quick question: Why did -c pass where running the script generates the uncaught exception?- Celebrate Intellectual Diversity	[reply] [d/l] [select]

`Can't use string %s as %s ref while "strict refs" in use` is a runtime error. -c is only for catching compile-time errors. There are many, many errors that can occur when a script is running but don't prevent the script from compiling. Here's another example: `$x = 0; $y = 7 / $x;` [download]	[reply] [d/l] [select]
