#
# Converts the list of paths in <path_list> into the native format
# and then joins them into a string suitable to be assigned to
# PATH (or PATH-like) variable. On Windows the string is joined
# using ';' separator. On other platforms with ':' separator.

# To avoid conversion back to a list object, the function adds
# separators in a form of generators: $<SEMICOLON> or $<COLON>

# Usage:
