=head1 NAME
Catmandu::Fix::paste - concatenate path values
=head1 SYNOPSIS
# If you data record is:
# a: eeny
# b: meeny
# c: miny
# d: moe
paste(my.string,a,b,c,d) # my.string: eeny meeny miny moe
# Use a join character
paste(my.string,a,b,c,d,join_char:", ") # my.string: eeny, meeny, miny, moe
# Paste literal strings with a tilde sign
paste(my.string,~Hi,a,~how are you?) # my.string: Hi eeny how are you?
# Paste works even when not all values are instantiated
paste(my.string,x,a,z) # my.string: eeny
=head1 DESCRIPTION
Paste places a concatenation of all paths starting from the second path into the first path.
Literal values can be pasted by prefixing them with a tilde (~) sign.
When a path doesn't exist it is regarded as having an empty '' value.
