The OOXML spec writes =@(expr) as =_xlfn.SINGLE(expr). Calc emitted the bare @ glyph on save and dropped the wrapper on load, so =@(F3:F5+0) fell back to a non-array context after a round trip and lost the authored value. Map "_xlfn.SINGLE" to ocSingleValue in the OOXML symbol table. The regular exporter walk now spells ocSingleValue as "_xlfn.SINGLE" and the import compiler recognises the wrapper, so a parenthesised operand round-trips with no further work. A small exporter branch wraps bare and function-call operands in the wrapper's own parentheses. OOXML files in the wild put the @ operand inside a redundant parenthesis pair, _xlfn.SINGLE((expr)). A post-compile pass on import drops the inner pair so the cell reads back as =@(expr). The helper takes a trigger-opcode list for reuse. testSingleOperatorXlsxRoundTrip covers the export path, testIntersectionOperatorXlsxRoundTrip covers the import strip from a fixture file.

Spreadsheet Application Code
You can dump some information in a dbgutil build:
Shortcuts
CTRL+SHIFT+F12
Dumps the column width of the first 20 columns.
CTRL+SHIFT+F11
Dumps the graphic objects and their position and size in pixel.
CTRL+SHIFT+F6
Dumps the SfxItemSet representing the cell properties' of the current selection as a xml file. The file will be named dump.xml
The Cache Format
ScDocument::StoreTabToCache allows storing the content (not the formatting) of a table to a binary cache format.
The format is column orientated which allows quick serialization of the table.

Functions Supporting Wildcards or Regular Expressions
As this comes up every now and then, and rather should be documented in an extra list of the Help system, functions that support Wildcards or Regular Expressions and depend on the setting under Tools -> Options -> Calc -> Calculate are those that in ODF OpenFormula (ODFF) are defined to depend on the HOST-USE-REGULAR-EXPRESSIONS or HOST-USE-WILDCARDS properties, see ODF v1.3 part4 3.4 Host-Defined Behaviors https://docs.oasis-open.org/office/OpenDocument/v1.3/os/part4-formula/OpenDocument-v1.3-os-part4-formula.html#__RefHeading__1017868_715980110
