I agree. For that suggest the following syntax (independent of this
proposal):
That is, support UDA for expressions.

void main(){
import std.conv:text;
int var=12;
@("syntax=python")
r{
def fun:
print(@var) #will expand to tuple element 12
print(@(var.to!string)) #will expand to tuple element "12"
}
.text
.run_python;
void run_python(string a){
import std.system;
system("python -c "~a.escapeShellFileName);
}
}
