Request option to put long function calls on multiple lines

This is something that we can't fix with the language.
Scriban is a dynamic language, so you can't distinguish an access to 2 variables on 2 lines from a function call:

With your request, the following existing code:

x
y

would translate to x(y) which would break all users. Also, x could be or not a function, and so you can't resolve this knowledge at compile time, you need to resolve it at runtime, hence why multiple lines is not possible.

There is a language mode (Scientific), that allows to call function calls with parenthesis, I believe that this one could be - or is already - supporting that.

Maybe we could go with Python's approach? In Python, you use a backslash at the end of the line. Literally, you're escaping the newline.

Scriban would count that as a newline only for the purpose of SourceSpan or reconstituting the original template. The parser would ignore that newline and treat it the same as any other non-significant whitespace.

really_long_function "This is" "a really" "long function" "call with" "lots of" "arguments that" "could really" "benefit from" "being spread" "across multiple" "lines so" "that I" "can use" "argument names" "for clarity"

Might become something like this:

really_long_function arg1: "This is"            \
                     arg2: "a really"           \
                     arg3: "long function"      \
                     arg4: "call with"          \
                     arg5: "lots of"            \
                     arg6: "arguments that"     \
                     arg7: "could really"       \
                     arg8: "benefit from"       \
                     arg9: "being spread"       \
                     arg10: "across multiple"   \
                     arg11: "lines so"          \
                     arg12: "that I"            \
                     arg13: "can use"           \
                     arg14: "argument names"    \
                     arg15: "for clarity"

Maybe, can't tell how much work that can be, could be complicated but PR welcome (no personal time to work on this)
