;{name}(\.{name})*
You can cpncatenate variables into strings:
"Send ";username;" a friend request"
but with variables that comply to the rules
for identifier names (as most variables do),
there is a shorter way:
"Send ;username a friend request"
This also works with arrays with keys that are
identifier names or natural numbers:
"Also ;friends.mine.12 is my friend."
For all other variables and arrays
and for any other expressions,
use the slightly longer concatenation syntax.
You can disable the ; syntax in three ways:
"write ;";"varname instead"
"write \;varname instead"
"write ;;varname instead"
all three render the text
"write ;varname instead"
not replacing ;varname with anything
Eas:
"Hello, ;name!"
";sts.mc messages"
PHP:
"Hello, $name!"
"$sts[mc] messages"
