So string eval works so long as the entire trailing code block is in the string, which gets pretty clunky for one scenario I'm dealing with. But it works, which is better than I've gotten on my own.
#!/usr/bin/perl use strict; use warnings; use Data::Dumper; my @data = ( {unit => 'S', value => 50, }, {unit => 'T', value => 60, }, {unit => 'Q', value => 70, }, ); LOCAL_BLOCK: { my $cmd; $cmd .= "local \$data[$_]{unit} = 'S';\n" for 0 .. $#data; $cmd .= 'print Dumper \@data'; eval $cmd; } print Dumper \@data;

I'll do some digging on the cited modules, to see if they work in my context.

[Corion]: TCLion: Whee ;)
[TCLion]: need to put like this : 2017-02-20 09:30:53
[1nickt]: That's why I asked if you are using DateTime. It has a large number of supporting modules (the author likes the term 'eco-system') so if you are already creating a DateTime obj from your dates, this module would read in the mnoron-formatted 1s seamlessly
[TCLion]: when I put the date together it looks like : 2017-Feb-24 (month is the problem)
[1nickt]: good luck, then.
[TCLion]: looking at DateTime documentation in monastery now
