prefix patterns

The blog explores simulating namespaces in Bash using `declare -n` combined with prefix patterns. Without native namespace support, the `declare -n` feature helps create namerefs for indirect variable referencing. This enables the grouping of related variables, such as server configurations, into a logical structure, enhancing script modularity and readability, particularly in complex or team-based projects. The examples discuss managing settings via associative arrays linked with namerefs, demonstrating an organized approach mimicking namespaces in other languages.
