That's the same variable. Use braces disambiguates when you mean when the |
| 13 |
variable is substituted in odd places. For example "$NAME's clothing" is |
| 14 |
different from "${NAME}'s clothing" in perl because single quote is an old |
| 15 |
way of doing scope resolution. |

Even in bash, you can experience ambiguity. ${DIR_WITH_END_SLASH}subdir is |
| 18 |
very different from $DIR_WITH_END_SLASHsubdir. Also, $HOME (and ${HOME}) |
| 19 |
are actually older than the ~ notation and ~ not immediately followed by a |
| 20 |
valid login name is always just a shortcut for ${HOME}. |
