> actual code being embedded inside strings
My view on this is that it shouldn’t be interpreted as code being embedded inside strings, but as a special form of string concatenation syntax. In turn, this would mean that you can nest the syntax, for example:
"foo { toUpper("bar { x + y } bar") } foo"
"foo {
toUpper
(
"bar {
x
+
y
} bar"
)
} foo"
"foo " + toUpper("bar " + (x + y) + " bar") + " foo"
